Do you pay attention or just rent?

"I'd like to watch this."

You'd like to preview this? It's always best to confirm these things. Nine times out of ten, it'll head off problems at the pass regardless of how coherent they may sound. That one time out of ten it doesn't help, nothing short of five consequence-free hours with an axe will.

"How much?"

You've been in before man, this is not your first preview. Perhaps you've forgotten the pricing. Two bucks to set-up, six per hour.

"That's for the whole movie?"

No, it's measured by the hour. It has always been measured by the hour.

Answering stupid questions is annoying enough. Doing so with a person who's been in several times before and has no excuse for not having a good grasp of the whole process is just gratuitous.
