1. Be sure to put the deposit receipt in a conspicuous position on the table, or you will find several waiters cleaning up the place where you just sat, like some big cafeterias. Because when the waiter sees an empty plate on the table, he will think that the people at this table have finished eating and left.

If some buffets have no deposit receipt, you can put your coat on the back of the chair. Prove that this position is occupied.

3. If you like to eat a lot of barbecue food in the buffet, I suggest you have a small drink after eating a small part, and try to choose soft drinks (because you eat a lot of barbecue without drinking, you may not be able to pull it out the next day).

4. Take less, not more. In the end, you will find that you suddenly don't want to eat this kind of food. This is fucking embarrassing. Even if you haven't touched it, you can't go back.

When barbecuing, there is too much oil to jump out, thinking that the waiter should add some salt to it, so the oil will not jump.
