> Well, the thing about both yellow and orange, is that there is no actual retaliation against the customer.

Yeah I like that part. Maybe the customer is having a bad hair day, maybe they are autistic or homeless. There is no need to kick them out or confront them if they haven't said or done anything bad. Just have a way to quickly pass the handling to someone else and move on.

Normal division of labor means you're going to get slower service from a manager than from a server. It's a simple math problem.

Most of the restaurants around here the manager is literally just standing there watching to see what's happening. If they were to wait my table, I'd expect to get awesome service.

Do you not think people won't figure this out, when they see the manager always serve them in a restaurant, but everyone else gets a normal waitress? When I ask that waitress for the check, and the manager comes instead after fifteen minutes, because he had to be taken from the back room and interrupted from balancing the days take, I won't know?

How is this a problem? If you actually have done something wrong, then realizing what's happening just means you're put on notice and you might want to take a hard look at your behavior. If you haven't done anything wrong and the server is abusing the system, then you either won't care, or you might choose to patronize the establishment less, either of which is fine.
