no. I dont think they put their ear up to the door. I have been to this place before and they sit in a chair out side the room. I cant remember if they shut the door completely or just leave it shut with a crack. Got a pill bottle that holds about 65mls. the noise of opening the bottle scares me and the little noise of carring it...it sometimes makes a little splash noise, but it not really that loud. I will just have to be carefull. I took winston's advise with the underwear and have been practiceing. My plan is to get in there open the bottle and piss with one hand and dump the sub in the container with the other hand at the same time. I'm doing this to cover the noise of dumping it. I just hope they dont have cameras or mirrors to watch me from another room. I'm pretty sure that would be illegal anyway.
