There's no way they'd be allowed to have someone staring at your vagina and urethra waiting to see urine come out.

When I had to drop for probation (I'm male), a cop stood behind me but that was it. That is completely different than a pre-employment drug test. If you have practiced your sub method and know that the sample temp is between 90-100 degrees (most important part), you will be fine. Good luck!
