Man: I've got those 20 bags of cement you ordered.
Sam: What 20 bags of cement? I ordered 20 bags of pretzels. I faxed my order to Amalgamated Snack Foods.
Man: Oh yeah, we often intercept their orders so we can push cement.
Sam: Maybe what happened is I faxed the wrong company.
Man: That happens all the time.
Sam: So you'll take it back for me?
Man: Nope. You still got to pay for it. Good thing it happens all the time. Here, sign here. I'll get the rest of it.
