Working at a gas station, I basically have to make sure I wear plain shirts with no pictures or writing on them. Why? Because every single customer will make a comment about it.
Here's a typical scenario:
Me: Good morning, sir. How can I help you?
Customer: *peering at my t-shirt* Old Navy...what's that? Are you in the military?
Me: Umm, no. It's a t-shirt from a store called Old Navy.
Customer: Well why is there a picture of a tree on it?
Me: I don't know, I just bought it like that.
Customer: *peering again* Old Navy...with a tree. That's weird.
Me: *wishing I was anywhere but here*
Usually I think the male customers 'pretend' to read my t-shirt so that they can take a glance at my boobs. Whatever they are doing, it makes me feel all dirty and violated when they look at my shirt.
So I've learned to wear plain shirts and sweaters, because 9 out of 10 customers will make comments about them.
I should get one made that says something like 'Stop staring at my tits, you pervert" or "Just buy your shit and get out" or "STOP STARING AT ME".
Hmm, I may be on to something here. What else could I get on a t-shirt to get my message across?
