I just received a call that the people in a smoking room are smelling smoke, go figure!
Did you explain that there are people who put things that cause smoke out?
I had a lady call me one time when I was on call and told me that here house smelled like smoke, and she wanted me to come out and check her a/c, I said "Maam, you need the fire dept, not me", and sure enough the friggin house was on fire
A few years ago, I got a call from an elderly gentleman who was very distressed. He had taken his ductwork apart and carried it all outside to clean it.
He couldn't figure out how to put it all back together, and couldn't remember what pieces went where.
It took me about a day and a half to sort it all out.
