Is the probation drug test supposed to be like that?

I was on 6 months probation for Poss. of Marijuana. So everytime my P.O. would make me take a drug test, i would go to a place and I had to pay to take a piss test, where I am lined up with like 6 other guys, and we all simultaneously pee in a cup while this fat employee looks at our wangs. I hate it because the person next to me looks at my wang.
