When I would get sent for drug tests for my employers I always overfilled the cup to the brim so when I handed it back to the piss police they would spill some. They always complained about me over filling the cup and I told them if they didn't like it they shouldn't have become a urine nazi. I would remind them to smell the sample to make sure it wasn't adulterated with bleach. I also used to piss on the walls and floor in their bathroom but never into the blue water. I invalidated a couple tests and got people written up for not following procedure in handling my urine sample properly. The place I went was supposed to do certain steps in a specific order and then seal off the sample in my presence and have me sign off on it. Some of the techs would want to do all the writing and signing in one shot. When they did that I made a fucking stink.
