That was a Saturday afternoon. I went to a fashion shop with my friend. I chose air of blue jeans to buy and pay for them at the cashier. Unfortunately, the shop assistant was careless. She forgot to take the censor clip on thu blue jeans. So, when I left the shop, the detector beeped. The security officer shout at me, "Hey, you! stop!", then he took me to the manager's room.
