I've been at several shows that have needed to stop... Sometimes for illness in the audience, sometime because of something involving a cast member, sometimes just set malfunctions. People didn't leave in droves, although I can't promise no one left...and if they did, they would not be entitled to a refund unless the show was actually cancelled. It's live theater, IT HAPPENS.
If we're not having fun, then why are we doing it?
