Dollar Tree review: Poor customer service

I put an empty can in the garbage inside dollar tree and right away the cashier Tondra became confrontational with me about it.
All she had to do is tell me not to throw it out inside the store and I gladly would listen.
Someone asked her where an item was while it was my turn and she walked slowly away to show her where the item was, she also took her time in the warehouse in the back and took her time walking back.
Most of the cashiers at this store are incompetent, rude, and just trashy.
I really hope you can improve the relations between us customers and the garbage off the street cashiers this store hires.
