Extremely rude staff

My husband just had the worst customer service from Collette at Roman's Pizza Elarduspark. On entering the shop, she was busy at the cash register, he greeted her twice and asked what time they close before she rudely decided to answer him. After arguing with him regarding the time, she extremely rude still in a horrible rude tone took his order. As a paying customer you DO NOT deserve such treatment an Colette surely doesn't deserve that job working with customers in that manner - shame on her! He got the manager's telephone number an will definately take this up with her and head office.
