we recently had a guy who was showering for over 2 HOURS (according to his neighbour) and when he opened the bathroom door it tripped the heat detector.

We have an ancient alarm system so even after the fire department shut it off, it needed to be re-set; the alarm technician had to be called out on a double-overtime as it was a holiday Monday. We charged it all back to the water hog who set it off.
