Is there ever really a case where the server is so bad that you have to take it to the manager? In my 14 years of frequently going out to eat I am hard-pressed to recall even one such instance. I think it is quite peculiar that the service of the server is perceived to be such a profoundly important component to the overall restaurant experience. Think of it this way: have you ever had to report a floor clerk at JC Penny or Sears to the manager, because he ruined your buying experience? Or a McDonald's employee or a Taco Bell employee? Front floor people are important, but it's probably not fair to place them above people in the background (cooks, dishwashers). This reminds me, my favorite restaurant (Pita Inn in Evanston Illinois) does not even have servers, you just pick your food up, go to the table and eat it. Honestly, I prefer the "experience" there over other fancy restaurants -- I just like to be given my food and eat it without interruptions, and without going through a sometimes-socially-burdensome task of having to decide on a right tip.
