You missed the entire point of the discussion. I'm not arguing for "not tipping well." I'm arguing that 10% = "tipping fairly" at buffets, and that anything beyond that must be earned through excellent service. I "tip well" when the server deserves it.I've heard every argument in the book for not tipping well.
Just yesterday my group of 6 tipped over 30% at a traditional table service restaurant (in my hometown). The waitress was outstanding, and deserved the tip. I did not base that tip on any assumptions about whether other diners were undertipping. I did not base it on any assumptions about whether she could "pay her bills." I based that 30+% tip on the fact that our glasses were never empty, she was friendly and attentive to our needs, and because a screw-up with my order was fixed immediately at her own insistence (I would have just lived with it).
