Oops, My Bad

I called and ordered pizza tonight. As usual, I asked for any specials and listened to him rattle off all the evening's deals. After that recitation, I was pleased to get a great price on 4 pizzas but when he confirmed the order he said to me, "And that is 4302?" "$43.02?!" I replied, obviously a bit flustered. "Why is it so much?" "Uh, ma'am," he answered, "that *is* your house number isn't it?"
