Keeping the Customer Satisfied

Lut has remarked the last several times he's ordered pizza on the speediness of the delivery: he'll get an estimate of 30 or 40 minutes, and then the pizza will arrive in less than 20. Last night, when the pizza showed up in 18 minutes, we got a clue as to why: "You were supposed to be my third delivery, but when I saw that tip, I decided to make you the first."

Apparently, tipping actually can make a difference in service quality. Who knew? :) Although I do feel a bit guilty about bumping other customers down the list, if that's what's happening. I prefer to root for "encouraging efficiency and productivity". =D
