Have you ever had someone else's pizza delivered to you at home (or vice-versa)?
A while ago, after having lived in our new home for about a month, my wife and I ordered a pizza for delivery. They warned us it would take a while because they were really busy that night. Then quite some time later - after seeing the delivery boy go past our house a few times - the delivery boy called and confessed to having delivered our pizza to the wrong house. He said he would be back to our house with a new pizza 20 minutes later.
To give some excuse to the delivery boy, our house is something like 123 1st ave, and he delivered to 123 1st place - which is one block from where we live.
Frankly, I was nonetheless annoyed that they wanted me to pay for the pizza (by the time it actually arrive almost 2 hours had passed since the time I ordered).
