Only person who MAYBE should be tipped is the COOK. Bringing plate to table is trivial - cooking is not.

Tipping is a scam in the age of wages and pensions

As someone who's worked in restaurant kitchens but did one single day as a waiter for training, I'd basically never work as a server, even for tips and the extra money.

Cooking was way easier.

I agree the whole tipping system in the US is a mess, though.
