I've had the fire trucks sent out after me three times (that I've noticed!). On none of the occasions did I declare any sort of emergency, although I did express some mild concern on one of them. I wonder how low the threshold is? - or whether they like to be called out at least a couple of times a day to relieve the boredom? - or what?
