Popeyes complaint: staff

We visited the Popeyes Chicken with in TI, Nevada. While ordering the girl at the register was very rude, we were talking to her being happy and asking her how day was going and trying to be friendly she just looked down and never acknowledge us in a polite manner. When the food was up the cook yelled order up, I stood there waiting and the staff disappeared 7-8 minutes felt longer, the cook in the back said the orders are up. She comes around corner with a biscuit in her hand and asked me if the cook said the order was up? I said yes he did, she popped the rest of the biscuit in her mouth, went over to the hand sanitizer and wiped her hands across her butt multiple time, gross, I guess she was trying to dry them off, but defeated the purpose of sanitizer. It was gross, then proceeded to get the French Fries out and put the order together. It was not a professional experience and I wanted to walk away but I just over paid for my meal since we were at the Casino location. I left with the feeling of being very sad, sad that this type of behavior is now acceptable. What happened to Professionalism and costumer service. I felt like I was a burden to her and was interrupting her snack time of eating a biscuit. . Makes you wonder what other type of behaviors go on when we are not looking. Thanks for listening
