Patron: Do you have a sewing machine here?
Me, very excitedly: We’ve bought one, but it’s not set up for use yet, but it will be soon, and we’re going to have classes in how to use it, are you interested in signing up for CLASSES?
Patron: Ummmmmmmm, no. *blinks at me*
He had, it turns out, actually asked if we had a SODA machine.
