Dollar Tree

I forgot my card in the house and i didnt notice about it. I only have 60$ on cash. I was going to buy some stuffs for our home, were in rush because my baby is sick, so we only get what we really need, and leave the other stuff in the cart, the 3 cashiers there get mad because we didnt buy all the things in our cart, one cashier shouted that "dont buy if you dont have money". What a rude attitude. Please make some actions of this.
