Two For One Pizza: Sounds Like A Good Idea, Right?

A fond memory: Aposto's, the narrow Italian bistro where we ate the other night, was once a far grubbier pizza joint called 2 For 1 Pizza, and the deal was this: when you ordered one pie, you got two pies for the price of that one-- in theory this was a good deal, but the same absurd dialog comprised every order . . . I'll take two pies . . . okay boss, two pies . . . so that means four pies? . . . you want four pies? . . . no, no, because then I'll get eight pies, right? . . . you want eight pies? . . . no I want four pies . . . okay, four pies . . . yes, so I'm only ordering two pies, so I get two for one, like the name, right . . . yes, then you get four pies . . . okay, just ring up two pies, okay . . . okay . . . okay . . . okay . . . just to be sure, I'm going to walk out of here with four pizza pies, right? . . . right . . . okay . . . right . . . okay.
