I knew about the sensor thing & have a story that goes along with it. Not too long ago I purchased a previuosly owned bag & didn't think I needed to check the pockets for sensors when it arrived. Well I went into the outlet & set off the alarm when I went in. However, since I was just walking in & had a bag w/an item I was getting a PA on, I didn't think anything of it & neither did they b/c they looked at me and said no biggy. But when I was leaving and walking out the door, the alarm went off again. I looked back to see what I should do and the manager comes over to "help" me. She takes my outlet bag, runs it over the counter, hands it back to me & I walk through again. Beep, beep, beep again! I was like damn, what is it? I figured it was my cell, keyfob, something. The manager then asked me if I've had my purse for a long time. I told her no (& didn't feel the need to go on about it being new to me but it was old, etc., etc.). Anyway, get this....SHE proceeded to GO THROUGH MY PURSE!!!!!!! I was like um......WTF are you doing!?!!!! I didn't say this b/c I was soooo shocked and couldn't believe what I was seeing! As she was rummaging through my belongings, zippers, etc., I begin to sense that people are watching "this" (we were right outside the front double doors). At that point I start pulling my purse back. Which I guess made her think something else b/c she then goes faster & faster looking through my bag (it was big - XL Lily)! Then I was REALLY like W T F?!!! At that point, I "took over" & reached into the interior zipper & found one of those little bitty sensors burried way down at the bottom corner. Never once felt it or saw it when I was loading my stuff in it. Anyway, I thought that was quite odd that SHE went looking through/rummaging through my purse instead of...PERHAPS ASKING ME TO GO THROUGH IT!!!
