Restaurant owners have a lot of nerve complaining about tipping.
You want your staff to get more money?
Pay them a better wage.
Tipping should be completely voluntary.
I don't see why bringing one meal should be grounds for paying a waiter fifteen per cent more. They're doing what they are hired to do.
That being said, yes, I do tip, because I often frequent the same restaurants so I want wait staff to like me, and I feel a little sorry for the staff, but I think tipping should be voluntary.
Expecting people to pay more than the stated price is a form of extortion.
