Personal space
In many European and American countries and regions, service charges are already added to your bill
In some Asian countries, such as South Korea, China or Japan, tipping is not common and can even be considered an insult to workers and should therefore be avoided
In Oceanian countries (such as Australia, New Zealand and Samoa), tipping is generally not expected or required. Some places, such as casinos, may ban tipping altogether.
In Western countries, it is impolite to sit at an empty table when someone is already sitting down, and even though restaurant tables are communal, this is considered an invasion of privacy.
But it's very common in some countries in Asia especially China
While kissing between male friends is a common greeting in some Middle Eastern or North African countries (such as Israel and Egypt), kissing between men and women in public is generally considered inappropriate and may even be illegal. There are exceptions, with the exception of Lebanon and Tunisia, where a man who kisses a female friend is considered "brother".
In southern European countries and regions, this is usually a greeting between friends. But it also depends on whether there are gender taboos in the country. In Italy and France, men will kiss male friends, but only female friends in Spain or Portugal. Kissing in public is generally considered inappropriate in East Asian countries.
In some parts of Latin America, cheek kissing is usually a greeting between friends of the opposite sex or between two women. A man who kisses a male friend like this is generally considered inappropriate.
Giving people personal space is an unspoken rule in the West, and getting too close to make people feel comfortable, especially heterosexuals, is very inappropriate.
In some countries, especially populous ones like China, personal space is seen as a luxury, while large crowds of people are seen as the norm.
bargaining
In the West, if you go to the supermarket, if you need this thing, then you have to pay the specified price. The only way to lower the price is to buy or find coupons at the time of sale.
Haggling over the price of goods is considered more normal in countries such as China, Turkey, Iran and Egypt.
Guest Meal Etiquette
In China, eating clean food prepared for you by your host is regarded as not full.
In Japan and India, it's seen as an insult to the host if your food isn't eaten in its entirety, which could mean you don't like the food.
Body naked
In some places, such as Singapore, nudity is illegal, and in some cases people can even be arrested for nudity in their own homes.
Some countries will demand more leniency. Hungary is famous for its bathing culture and the country is full of hot springs. Not only is it considered normal to change clothes in public, the country even has spas where customers are not allowed to wear swimsuits, as this is seen as an impediment to the development of spas.
