I used to manage a Papa John's. Guy called in the middle of the Super Bowl and ordered 15 pizzas; all 1/2 this and 1/2 that. I explained to him that due to the increased volume of business due to the Super Bowl, the added complexity of his order, and the added fact that he was ordering a large number of pizzas, it would probably be at least 45 minutes to an hour before his pizzas were delivered.
He immediately became extremely irate and said he expected them to be there in 30 minutes or less or they would have to be free.
I explained for the umpteen thousandth time that the 30 minute or free guarantee was a promotion that Domino's ran in the 70's and early 80's, that we had never honored that promo, and that even if we had we would not be that night due to the Super Bowl.
At this point he complained that he had a whole Super Bowl party and was depending on our food. When I explained to him that so did MANY other people, all of whom had ordered before him, he decided this was a good time to start threatening me.
He threatened to come up to the store, shoot me, then go to my house and rape my girlfriend. Due to problems we have had in the past, our calls in this particular store were recorded. Since I already had his name, address, and phone number from his order, it was very simple to arrange a "delivery" for him.
His delivery was a couple of sheriff's deputies to arrest him in front of all of his friends. For some reason he didn't order from us anymore after that night.
