I have been volunteering with a community theatre in my area for about 6 years, and I have seen some stupid, but I almost laughed out loud at this.
First some background: when you show up after a show has started, you have to wait with the House Manager for a certain window when you can be seated. This is really annoying when you have a large group.
For one of the shows in our Children's series, a lady showed up with about 10 kids about 15 min. late. When told she had to wait until the proper moment when they could enter, she responded wit
"Well aren't there previews?"
Umm, no, this is live theatre. Plus, we haven't even cast our next show.
