I've been back at least a handful of times since this experience and was told unfortunately it was their summer (high school) help and that he knew who the person was (sounds like I wasn't the only one unhappy with her). I was apologized to for the awful service and assured this person wasn't there anymore.
Every since this lousy worker has left the phone is answered promptly to take my order and when I pick it up someone has been at the pick-up counter or there shortly after I arrive. Pizza is terrific as always!
