My freshman year, I went to the UCI bookstore, rather the computer store to get floppy disks for a class. Anyway I was already holding a bag of some sort, I gave the cashier the floppy disks and the money to buy it. Got my change back and the cashier placed the disks on the counter. Not realizing the disks were on the counter and not in the bag I was carrying, I walked away. It wasn't unil I was more then half way to the doors that lead to ring road, that the cashier yelled out that I had left the disks on the counter...

1. felt stupid getting the change back and not the disks too
2. the bookstore has cameras so its on tape somewhere
3. I probably was a cashier's "stupid customer" story for awhile

that's my 2 cents
