I actually discussed this with an LT on my local fire dept this weekend. I teach him bagpiping, and after the lesson we got around to talking about "false" 911 calls. They regularly get calls (the calls for 911 come into the FD) for people who have locked themselves out, a few to have someone come over to change fuses, lightbulbs, things of those nature, a woman called recently to complain about the color of the fire hydrant even (they recently painted their home, and the hydrant now clashed colors). Not that this is exactly on topic, but people seem to use the 911 system not for emergencies, but as a complaint line. And I am SURE that this doesnt just occur here...
