Those are things happen with good management, they have little to do with how hard an individual employee is working at a given time.
Besides the claim wasn't waitstaff gets "extra" tips for working hard, the claim was that waitstaff is tipped because they work hard. Don't move the goalposts.
>I honestly don't understand how you can say tips are not proportional to level of service and how level of service is entirely detached from working hard.
I tip the same if my service is shitty, I am not going to put an individual employee in a position of taking a pay cut when I can't know the exact reason something went wrong. I don't know enough about their operations to be punishing individual employees. Even if I could tell if it were an individual employee's fault, most places pool tips, so I'd be punishing the other employees working at the same time. So everyone gets the same tip from me.
I also simply just don't enjoy LARPing as a lord of my personal fiefdom.
Again, you get good service with good management, simple as that.
