I had this exact experience at the movie theater, yesterday. There were two cash registers at the concession stand, but there was some ambiguity as to whether the second one was staffed. So, at first, like everyone else, I queued up at the first register. I asked around and nobody seemed to know whether the second register was open.
However, I noticed that the line on this register was moving rather slowly, and not wanting to be late for my film, I decided to take a risk and walked up to the second register. Lo and behold, it was actually open, and I had my popcorn in about a minute. If I hadn't been late for my movie, I don't think I would have gone to the second register.
