We used to have calls like that for a similar establishment and then one day, it really did burn down.
I remember many years ago a hospital had an old fire alarm system. Everyday it was giving out false alarms, sometimes two or three times a day.
One day a alarm call came in and before any units got there the hospital called reported it to be another false alarm.
The battalion chief must of decided to play it by the book and sent the first due in to check.
The first engine reported back that there had been a small fire and had been put out by staff members.
The battalion chief confirmed there had been a fire and no other resources were needed, and he was on his way to have a talk with hospital staff.
A few weeks later an article in the local paper announced this hospital was upgrading their fire alarm system.
I heard though the grapevine that the city told the hospital that any call for an alarm would have a full response and the hospital would have to pay for any false alarms that should occur.
