Why won't the boys be doing their bowling at Rileys?

The boys won't be bowling at Riley's because Stanley had some trouble with Riley, and he was the captain.... so.... they won't be bowling at Riley's because Stanley doesn't want to.

QUIET IN THERE!--We've got a noisy woman on the place.--Go on, Mac. At Riley's? No, I don't wanta bowl at Riley's. I had a little trouble with Riley last week. I'm the team-captain, ain't I? All right, then, we're not gonna bowl at Riley's, we're gonna bowl at the West Side or the Gala! All right, Mac. See you!
