I wish it were possible to leave 0 stars. I don't even know where to begin. First, the woman in front of me had her order messed up and was overcharged by over $10. They wouldn't fix the price because they "had already cashed the order." This is what happens when you employ 16 year olds to run the cash register. Secondly, while waiting for my pizza, the manager was screaming at his employees saying they should have things ready and they could if they weren't F***ing ret**ds. There were children in the lobby and I was mortified for those parents. Third... while I was leaving I was almost rearended twice by a delivery driver-- did you know there are stop signs in the parking lot? Huh.. strange. Well then he cut off two drivers on Blue Diamond and did not use a turn signal once. I wrote down his license plate number in the event anyone is interested. I was absolutely disgusted by the experience I had, and it's a shame because the pizza is well priced and always tasty.
