I’ve done it with impulse purchases before. Got in my car and felt guilty about spending the money.

I've had to shop for a specific sweater for the kids before, event at school, ect. I'll have looked through like 8 stores and finally come across one that's VERY close to what I need. Purchase, Literally the next store I browse through for something else, THEY HAVE IT! Walked back to other store and returned within 10 minutes. I'm already at the mall that's 20 minutes away, why TF would I hold onto it for the next time I shop? I found what I needed in a store that isn't specific for kids so I need to return! OP's Situation may have been Cashier waited on her and helped her try stuff, and coming back 5 minutes later to return she wasted her time. Cashier was still an asshole, that's literally what shes paid to do; sell and return.

It's shoes. Maybe she wore them and found out they weren't very comfortable?

heard of commission?
