Here's your chance to preserve your dumb* patron question for posterity!
You know the ones:
"Is that a real fire/ sword/baby?"
"Aren't you hot in all that clothing?"

*As funny as some of these stories are, try to remember when dealing with the public there are no real "dumb" questions.
Most are just poorly asked. When someone asks "Is that a real fire?" what they may be intending to ask "Is that fire just for atmosphere, or do you actually use it for cooking?"
