Unless they're unlucky enough to work in a place where tight-arsed gamers come and sit for hours.
It's the old problem again. Anyone can do well, but not everyone can do well. That's an important distinction. If someone works in the flash hotel with the $200 tip on one meal, then someone else has to work in the Denny's with the fat-arsed nerds who sit there for hours and just get water. But both are doing an honest day's work.
If it's so fair and reasonable, why do we only do it with waitstaff? We could easily extend it to other workers. IT support, for example, could get $5 an hour, and then make the rest up in tips from satisfied customers. Doctors could get $10 an hour and make the rest up in tips from patients made better, or from families who are grateful the doctor at least tried. Coal miners could be paid $1 an hour and make the rest up in bonuses for productivity. Teachers could get $4 an hour and then more in tips from parents grateful that little Johnny can now read.
If low wages + tips for good or productive work is such a good way of doing things, why aren't other kinds of workers asking for their industry to change to match it?
This reminds me of that thread we had where all these people were saying that teaching was an easy, well-paid job - yet strangely they weren't keen on doing it themselves. Funny that.
Everyone deserves a decent wage for an honest day's work - whatever that work is. Waitstaff have a shitty job. Chefs like me just have to cook the food, we don't have to smile while doing it, and don't have to deal with customers being stingy, picky, ignorant about food, groping us, or anything like that.
