I agree that a "strong-armed" request for an excellent rating is inappropriate. HOWEVER, I can understand why servers cross the line. In my position, a significant quarterly bonus is based in part on surveys completed by clients. The difference between a "4" and a "5" can be several thousand dollars! I have never asked a client for a "5", but I have been very frustrated to hear from people who have given me a "4" later say that the service I had provided far exceeded their expectations and surpassed the service provided by any of our competitors. The frustration is that, if they understood the scoring system, they certainly would have given me a "5", but everyone's definition of "5" (or "excellent") is different, making it very tempting for the subject of the survey to "coach" those being surveyed!
