Jockstrap memories

So have you ever had one of those random memories kick in for no good reason at all? You have? Me too!

I was at a Little League practice the other day and they were talking about how one of the kids needed to buy a jockstrap. Well that triggered the following memory from my City Sports days:

I was working at the register when a guy came up with an exchange. Now, since I had a very solid personal policy about not paying attention to customers, I didn't pay him much mind at first when he set two jockstraps down on the counter.
-"Umm... I need to exchange these," he said.
-OK.
-"Not for me. It's for my son... my... friend... I mean... it's not for me. For someone else I mean... I need to exchange these."

Now he had my attention. I looked at the two jockstraps.

He was exchanging an XL for a Small.
