I was in sales for a very brief period when I was young...er. One of the first lessons I was taught? Never mention the customer's name more than twice unless you have a need within the space of five minutes. You should have kicked this guy where it hurts once he rang that bell the third time. OR did I say "ring that bell" in the wrong place? I know you're nice, but there is a limit.

Hissy fit? Sure. On the phone, maybe. Get a little kung-fu goin' next time. You know, these guys all get together at the same bar every night. The word goes around.
