By way of background, 90% of Fire dept calls are medical in nature. The reason the fire dept responds on medical incidents is that the response time is almost always much faster. Often the incident is not a true emergency, but the law is that we cannot leave a patient until we have turned them over to an equal or higher medical authority.
So the story I heard was an engine company late at night/early morning standing by with an elderly gentleman who needed to be transported, but the ambulance was substantially delayed. As they are waiting, the captain spots a bowl of peanuts on the nightstand. He's hungry, what would it hurt to have a couple of peanuts? He has a few, then a few more. Soon, they are all gone. Chagrinned he confesses to the old man. "I'm sorry, I've eaten all your peanuts. I just couldn't stop eating them"
The old man is not upset and tells the captain, "That's ok, I know what you mean, but I can't chew them anymore, I can only suck the chocolate off them"
