True...but if you have lived in the USA for a month, you know that it s more than common practice to tip a server. And it is far worse being a server than working in a department store helping customers.
These people are trained and thus get paid more. Doesnt take much brains to be a server.
A maid and butler get paid to do similar things for people...same concept. If you dont want to pay the maid/butler, then dont hire them and make your own food and cleanup after yourself.. Dont want to tip, then stay and home and cook your own food and serve yourself.
Restaurants are there for convenience and entertainment...as such, you have to pay for it like anything else.
You can get an assistant job at a care center with no training as well.
