I stayed in a hotel where the fire alarm went off in the middle of the night. There was no fire. On investigation it turned out another guest had started filling the bathtub, laid down on the bed to wait, and then fell asleep. The water spilling over triggered sensors in the floor meant to detect if the room's fire sprinkler was spraying, and trigger the alarm.
I imagine the hotel will care once that melts.
(The front desk might be a better option, though.)
