Customer: “What time does the film start?”

Me: “The film starts fifteen minutes after the time on your ticket. There are fifteen minutes of ads and trailers.”

Customer: “No, I said what time does the F-I-L-M start?!”

Me: “The film starts after fifteen minutes of trailers, so fifteen minutes after whatever it says on the ticket. Your ticket says 3:30 pm, so the film would start at 3:45, okay?”

Customer: “Don’t blind me with science!”
