You should always leave a tip at a sit down restaurant, but it's not always required to be 20%; you can give what you feel warrants the service offered -- for example: excellent service 20%+, ok service probably 15%; not great service 10%. I have gone to Chinese buffet restaurants that the waiters say something like "give me more tip" lol, so might be that they are told to ask for more? Idk.
You are suppose to give 20 percent tip whether it’s buffet or not. That’s the bare minimum
That’s the worst, why anyone obliged to give TIPs, it’s about service and they charged for food and service. It’s our wish what amount we give.
