Tipping is a way for owners to get around paying half their staff & servers dont want tipping to stop because they generally make a lot of money for not that difficult of a job. One study I saw ( i cant find it now) said servers generally make like 2.5 times more than back of the house staff. So any time the subject of tipping comes up, you have owners online lying saying they'd go out of business if they had to pay staff, because they make like no money (even tho other countries have restaurants, pay their staff and somehow stay open), then you have servers trying to shame you if you dont tip a high percentage( they constantly try and up it every year).
What I always find funny is the threads about tipping on reddit. All the servers flood it going on and on about how much their check is (conveniently leaving out the amount of tips they make) and how difficult of a job it is. But when people challenge them on said difficultly, they never have much to say, other than they have to stand a long time.
Whats interesting is the last time server pay was raised, was like 30 years ago. When they announced that they're planning on raising it, the restaurant industry used the same scare tactics they use today and other industries use for min wage. Talking about if its raised they'd have to fire people and go out of business, ect. They raised it anyway, to what it is now, then magically nothing happened after that.
