Jail anyone who skims tips a minimum of 5 year or summarily shoot them at dawn.
Wait staff are your sales people and should be justly rewarded for upselling customers as well for giving them a reason return
NOBODY tips so the owner can skim some of it. That’s as sleazy as it comes.
One of my favorite eateries used to pool all tips, to make sure that the cooks got a cut. They had a lot of waitress turnover, but since it only had a capacity of about 45 persons, that was likely to happen anyway. But I’m not sure how this no-skimming rule pertains to the usual gubmint shakedown of restaurants and their employees, regarding uncollected income taxes on tips...
If you pay with a credit card and you tip $10, the restaurant has to pay the credit card processing fee on the entire bill -- including the tip. They end up paying this cost themselves.
