>>212902165In any other type of situation the point 3 is dealt by consumers not returning to places with bad service. That's the incentive to do a good service.
I don't know about the point 1. If I was a waiter I would want a more stable and reliable income source instead of my boss pocketing the entire profits and treating me essentially like an outsorced worker who needs to rely on the good will of extorted clients paying twice.
So this whole scheme only seems to benefit the restaurant owner in point 2
