The Baseball Stars

When I was working today, I decided to buy a drink becouse I was thirsty. I used the paybytouch to pay for my soda, and it says unathurized transaction. Usually if it says this that means that an account is overdrawn. I knew I had money in my account to cover a soda. 15 min later, a pizza man came in the store, and said is Russell her. He said I orderd a pizza. I know I didn't. Stewed asked me to sign the receite. I asked, why I didn't buy anything. He said just sign, its already paid for. The pizza man said it was for linda. I thought maybe somebody used my debit card without permission. I was totally confused. I checked my bank account online when I got home, and it was fine. I was very relieved to see everything was ok. I thought maybe somebody at work cleaned my bank account out, but that wasn't the case. Why would somebody say the pizza is for me and then have me sign somebodies receite if it wasn't mine in the first place. What do you think.
