It really just depends on where you work and your demographics.
Young black male in rural city? Lol you're fucked. Attractive young white woman in dense urban center at trendy expensive restaurant? Absolutely crazy amounts of money.
I've known people who graduate, get a job in the field they wanted and then quit and went back to serving because they fell into the right demos and location.
The tipping floor is the lowest it can possibly be but the ceiling is extremely high. And it's largely based off unfair reasons.
It allows conventionally attractive young white unskilled workers in dense enough areas to do that.
