I can't run, I can't hide, even if I wear different clothes, they find me

How do they always find me? Even if I am not working that day, and I am following three of my co-workers around the store, customers will let them go by then ask me to find them a shoe. Is there some sign stapled to my forehead that others can read and I can't see? I guess it's because although I sound like an asshole in these blogs, I look like a nice, knowledgeable young man in person. I guess my smug demeanor and ample eye contact make me an easy target. Ask the guy with the name tag, tie, price gun and worksheet for a shoe, not me. I'm just an unexpecting bi-stander like you in this situation. I don't want to help you, and I'm not going to, but good luck with that!
