Once customers put the change in, they will get timely and thoughtful service from the waiter. Since then, this practice has gradually extended to other service industries, and has rapidly continued, becoming a routine form of etiquette for many countries in the world to thank service personnel for their thoughtful service. It is very impolite to accept services abroad without tipping, because tipping is very important for service personnel, and a large part of their income comes from tipping. Of course, tipping has another purpose, which is to make you eat more comfortably and avoid a lot of trouble. Mel is obviously experienced: "After finally persuading the girl of your dreams to have dinner with you, you should never think that you just need to book a room in a luxury hotel." No matter how luxurious the hotel is, there are worthless seats deliberately placed by the door of the kitchen entrance, so that you can enjoy the noise of broken cups and plates and abusive cooks while eating. Besides, you can't expect faster service, which is a common practice: the table closest to the kitchen must be served last. In order to avoid these tables, you should have the money ready when the foreman greets you. "On the question of how to tip, etiquette experts gave the following suggestions: ● When eating in a restaurant, customers usually need to tip the service staff about 10% of the total consumption. ● Many people often say, "Keep the change! "When paying the bill after consumption. This is equivalent to telling the service staff that you don't need change to keep it as a tip, which is a common tipping method. If you pay by debit card, you can write down the total amount including tip on the bill before signing. ● It should be noted that some restaurants will directly include the service charge in the bill. But tipping is not the same as service charge. The service charge is the surcharge paid by the customer, which is generally 10% ~ 15% of the consumption, and is listed at the end of the bill. Generally speaking, if the service charge of 15% is listed on the bill, there is no need to tip. If the service charge is only 10%, customers usually have to add 5% to the tip. ● In western restaurants, many people put tips on check-out plates or hand them directly to service personnel. In fact, these two practices are somewhat irregular. The correct way is to put the tip on the napkin, or under the plate that has finished eating, so that the waiter will take it away when he comes to clear the table.
