Or you can tell them you want to speak with their supervisor. They usually do not want their boss to come out there for their stupid BS. tends to shut em up.
As long as it is stupid BS and not a true violation, they will and do request for their supervisors and will make you wait and in the meanwhile they will look for more violations while you wait. A bonus is never ask to see his supervisor if he's got stripes, you're already talking to him.
