I walked in and out of Macy's at Northeast mall a couple of times yesterday after making a clothing purchase. I noticed the security alarm seemed to correspond with my entry/exit but didn't think much about. At least until I pulled out the purchase today and noticed the security doohickey was still attached. (Yeah, I paid for the clothes - don't get the search warrant.)
But I didn't really experience the joy of Christmas Eve a moment ago as I tried to remove thing. Sheesh. I finally had to take a hammer to dang thing. (Above.)
