Unfiltered Story #199925

I am on an ushering shift, and standing at the ticket check. One of our popular films has a short turnaround, so people are waiting to go in before the last showing finishes. My coworker radios me to let me know she’s finished cleaning it.

Me: Anyone waiting for Screen 5, [Film title]?
Customer: (jumps up from the chair and rushes over)
Me: (sees ticket) This is Screen 3 [Completely different sounding film]?
Customer: Yes.
Me: …Okay (reads seat number off) Enjoy your film.

The film they were seeing was halfway through the trailers, and they could have gone in nearly half an hour ago. I have no idea why they were waiting, nor why they suddenly jumped up when I called out a different film.
