At a previous employer, some years ago now, the building we were in generated false alarms (and a few genuine ones - the wiring was pretty old).
The thing I remember most was the sight of us standing in the car park and watching an ice-cream van come tearing round the corner. It regularly beat the fire brigade by minutes - even though the fire station was only a mile or so away.
Full credit to the guy's entrepreneurial spirit ("there's a bunch of people standing around without much to do, it's a warm day, Bingo!").
Sad to say there wasn't a burger or kebab van appearing in winter :(
Nowadays with encrypted radio I don't suppose the opportunities are there.
