1. Did you get scanned with a metal detector for a regular pre employment non DOT test? I fitted a brass barb to my container for vent purposes in draining. 2. Been practicing, got the temp down (heat pad not even really necessary) but pulling out bottle and doing the transfer seems cumbersome if using a toilet with a door open and somebody being around. I can only hope for a more private opportunity to test. What were your experiences regarding this? 3. Suggestions for aiding in the transfer if a not so private test is given? Obviously, I really hope for a "behind a closed door" type of test. 4. Can you describe what you did from the time given the cup to the time you hand the cup over and passed? I tried a search for this but nothing useful came up, except for one thread where a guy said the light had a fan wired to it. Thanks. PS, I had posted this on another forum, but after over 480 views had zero replies, giving it a try here. Thank you.
