Working as a Cashier

My first job after I graduated from College was a department store cashier. I had fun with that job because I get to meet lot of people everyday and I don't get bored. That when I started knowing a lot about computer because a few months after I started working there, the store upgraded their cash registers to the latest models so the cashiers were trained on how to use it. But my most favorite about that cash register is the barcode scanners. It still amazes me how it works.
