I've occasionally had this happen to me too.
Had it happen to me the night I got my phone. LP Guy at BB said to me when I set anti theft alarm off "Oh, don't worry about it. Your Droid set it off." Like it was common or something. I totally forgot about it til just now.
I had a pair of shoes that would set off every store alarm I walked in/out of. Can't remember the brand (Thom McCan maybe?). But it was quite annoying. I have yet to experience this with the DROID.
A gun in the hand is better than a cop on the phone.
