Being nice doesn't pay

This morning on my way to work I stopped at the bagel place. Standing in line, I noticed a twenty dollar bill in one of the muffin bins. Score! I furtively snatched picked it up and (seriously) considered using it to pay for my breakfast, but my goody-goody side won and I decided to turn it in. I really doubt anyone will claim it, but I figured I could use some Karma points. I handed it to the lady at the counter and told her where I found it. She tucked it under the edge of the cash register and said, "Oh yes, someone lost this." (Um, yeah that's why I turned it in.) She then proceded to overcharge me for my bagel. F U Karma!
