Dollar Tree

I went to Dollar Tree to see what was new. And I saw some T-shirts sitting on a register so I asked Artie if I could see them. She said yes as long as you fold them because I just folded them. That really upset me because I'm a customer not a worker. She has no right telling me to fold them, when it's her job not mine. I saw her being rude to another customer. If she don't like her job she needs to quit, this is so unprofessional of her to talk like this to customers, who are paying money. Someone really needs to talk to her about professionalism.
