I do remember being surprised the first time I heard some foreign friends complain about American waitstaff. They called them nosy, intrusive, bothersome, and constantly interrupting. This from people who ate accustomed to 2 hour meals in nice restaurants. On the flip side, my trip to post communist Hungary was met with waitstaff that was surly, slow, bored, and uninterested. The food was wonderful though!
So your complaint is that the American model of waiting is intrusive, bothersome and generally inferior to the European model?
If that’s your point, then go ahead and make it. I’m sure Obama would agree with you.
As for your other point, it still seems like you want to pocket the leftovers from your cheapskate tips in order to keep more of your per diem. You still haven’t given us a reason to believe otherwise.
