Except you have to tip, because tipping is baked into the laws in the US. Tipped workers have a minimum wage of 1/3 of the regular one. Not tipping even the minimum, say, 12% is basically a crime.
Or, you could argue that the existence of such low minimum wages are the true crime, because now you have this shitty Nash equilibrium where you must beg for tips because everyone else does.
"Buy beer at our place. Pay us 5 units of currency and we will get you this beer."
There's absolutely zero reason for things to be more complicated than this.
