1. Tipping Etiquette
Offering tips to service personnel like waiters or taxi drivers can be either generous or offensive depending on the country you're in.
- In general, in Western countries, you might tip a hefty sum to service staff. A service staff might even feel insulted if they believe they're tipped too little, and in many places, tipping is even enforced for large parties. Fast food workers are usually an exception to this rule and might even be penalized for accepting tips.
- In many European countries, a service charge is already added to your bill, but sometimes you might still need to give a tip. Hence, patrons will have to give a smaller tip compared to their American counterparts. In some places, like the UK, service charges aren't always customary and often substitute for tipping when it's brought up.
- In some Asian countries, like South Korea, China, or Japan, tipping is often uncommon and might even be considered offensive to the labor force and should be avoided. This indicates that some countries in this group may address the issue by implementing a service charge upfront before the work is done, so it isn't seen as a reflection of the worker's performance.
- In countries in the Pacific region, like Australia, New Zealand, and Samoa, tipping is often not obligatory. Some places, like casinos, often completely prohibit tipping.

2. Cheek Kissing
- In Latin American countries, it's often a greeting between opposite-sex friends or between two women. A man kissing a male friend like this is usually deemed inappropriate.
- In some Middle Eastern or North African countries, like Israel and Egypt, a man kissing a male friend is a common greeting, but public displays of affection between a man and a woman are often frowned upon and may even be illegal. There are some exceptions, such as in Lebanon and Tunisia, where a man kissing a female friend is considered “brotherly love”.
- In Southern European countries, it's often a greeting between friends. Whether there are gender restrictions or not varies from country to country. Men will kiss same-sex friends in Italy and France, but only kiss opposite-sex friends in Spain or Portugal.
- In general, in East Asian countries, public kissing is considered inappropriate. Some exceptions where cheek kissing is common include the Philippines, East Timor, and certain regions of Indonesia.

3. Table Sharing
In the Western culture, sitting down at a table when a family is already present is considered rude, and although some restaurants have communal tables, it's often seen as an invasion of privacy. However, in Japan, seating complete strangers at the same table is commonly practiced in crowded restaurants and is seen as an efficient way to get everyone served as quickly as possible.

4. Bargaining, Negotiating Prices
In the Western culture, when you go shopping, you usually have to pay the predetermined price for an item you want to buy. The only way to get a discount is to purchase during a sale or find a discount voucher. However, bargaining for the price of an item is much more common in countries like China, Turkey, Iran, and Egypt. In fact, in many places in this group, not bargaining for the cost of something might mean you could end up being ripped off when shopping.

5. Personal Space
In the Western culture, giving people personal space is an unwritten rule, and getting too close to someone to make them comfortable, especially of the opposite gender, is highly inappropriate. In some countries, especially those with large populations like China, personal space is considered extravagant, and people congregating into large groups is the norm.

6. Nudity
- In some places like Singapore, nudity is illegal and prohibited to the extent that there are cases of people being arrested for being nude in their own homes.
- Some other countries are generally a bit more relaxed about this. Hungary is known for its bathing culture, and the country boasts numerous spas. Changing clothes in public is not only considered normal here, but the country even has spas that prohibit guests from wearing swimwear, as it's seen as hindering the proper functioning of the spa.

7. Finishing All Food on Plate
If you're a guest at someone's house and you're given a plate of food, try finishing that plate of food to see whether you're considered polite or offensive. In China, finishing your food is seen as you still being hungry and the host hasn't fed you enough. However, in India and Japan, not finishing your plate is considered an insult to the host, as it suggests you don't like the food.

8. Loudly Shouting
In China, shouting in public is completely normal. For example, when dining out, shouting at the waiter is considered a perfectly acceptable way to get their attention. After all, you can't expect the service staff to read your mind and know what you want. However, in the Western culture, this is seen as impolite and disrespectful to the staff, and people usually wait for the waiter to come to their table to offer feedback.

9. Sharing Utensils
Some countries, like North and South Korea, have a culture of sharing utensils. When dining with friends, everyone at the table often shares a large dish, and people may even use the same utensil to portion out food. Conversely, in the Western culture, this is seen as unsanitary and frowned upon, even within families.

10. Even Traffic Light Colors Differ Worldwide
In many Asian languages, turquoise and green are seen as shades of the same color. For example, in Japan, this has led to complications in designing traffic lights here. Technically, regulations often require the 'go' light to be green, but in Japan, turquoise is considered the best color for visibility. Another note is that light turquoise and dark turquoise are often seen as different colors (similar to how red and pink are seen as different colors).

11. Suppressing Anger Outbursts
In the Western culture, a woman may appear cute or childish when she wants something or just to appear shy. In China, it's a completely different art form, where it's very common to see mature women throwing tantrums in public just to get what they want, such as a new dress or a gift. And this isn't just tolerated: women who don't occasionally display such tantrums to get what they want from their man are often seen as lacking loyalty. In a way, this childish behavior reflects the responsibility of a man when providing for the women in his life.
