There was a guy that came into the Chipotle I used to work at and would ask for extra sides of your cream to go in addition to the ones in his bowl. At Chipotle the non proteins don't technically have a limit of serving/being charged extra for. We would start stacking the cups on the counter for him to take and he would chug them like a shot, one after the other. He would do about 10 or so until my manager would come over and tell him he has to stop and take what he has.
