I was at The Sports Authority buying a bat, and this woman came up to me holding an old glove and asked,

"Do you know where I could find a glove like this?"

I said, "No, sorry."

Angrily, she responded, "Well, do you think you could you find someone that does?"

I said, "Yes, I suppose I could, but I don't work here."

She sheepishly apologized and explained that she thought I worked here because I was wearing a green shirt. I don't know what that has to do with anything, since none of the employees there wear green shirts.
