the greens, the population, the beeps

i'm pretty sure someone who's normally hanging around with me in the city notices that everytime i enter or exit the shops ( eg. general pants, city beach, universal store etc), the alarm beeps. it's been REALLY REALLY annoying me. and..my friends as well, for sure..lol.. it's so embarassing when you enter a shop and the alarm beeps. but it won't happen anymore!! HAHA!!
one of the shopkeeper said that probably there's a..security tag? i'm not sure what to call it but i guess you know what i mean. it's like a barcode that sticks to the things in the shops. so i checked my bag and everything inside it..and i found out that it was there, inside my wallet!! omg...i felt so stupid for not knowing that the tag was still in there...in the bottom of one of the card slots..and i have been using this wallet for 2 years!!
so, sally spent around 15 minutes to take it off..(damn, it was hard..) then she shops peacefully ever after...hahaha..
