Clearly, you have never been a Server?
Being a Waiter/Waitress is usually SUCKY!
It’s a very difficult job, people are demanding, most places do NOT pay well and they rely on tips. (Unless live in a country which isn’t a tip based culture/society like Japan.)
And Servers have to deal with lots of difficult, jerky people!
If lucky enough to not have to work a service industry job, I advise TIPPING WELL, esp if wealthy!
Especially during the holidays. They will appreciate it and can use the money.
