I used to work at Old Navy. I once had a customer who wanted to buy a onesie for her kid. She found one she liked and put it on him before paying for it. That, I didn’t care about. What bothered me is that she assumed that it was on sale. It was not.
Me: Okay, so that comes out to $12.50 (or whatever. I really don’t remember the price. Too long ago.)
Her: Whoa whoa whoa, what? No, that should be $4.99. It’s on clearance.
Me: Hm, it says here that it’s full price. Let me head back and check the sign.
So, we go check the sign, and come to find out, this was a brand new item (there was a whole rack of them), but some other customer put this one package in with the clearance junk (along with a bunch of other stuff that clearly didn’t belong there). I pointed out where the item was actually from and indicated that it was new.
Me: Oh, it looks like another customer misplaced this. Sorry about that, but unfortunately it’s still full price.
Her: EXCUSE ME? So, you’re telling me I have to pay for someone else’s mistake?
Me: Well, yes. We can’t just give you a discount just because another customer made a mess.
Her: This is ridiculous! Let me speak to your manager.
Me: That’s me.
Her: Ugh! Fine! I’m never shopping here again!
And then she proceeded to undress her child and leave the store.
Another time, I had a customer get upset that something wasn’t on sale. She picked up new jeans and brought them to the register. They shared at able with camis, which were something like $5. SHe was outraged that the jeans weren’t $5. I took her to the table where she found them and pointed out that yes, the sign did in fact say, “$5 CAMIS”.
The customer put the pants down, looked at me, and said, “Do you ACTUALLY expect me to read that?”
“Yes, I do.”
