No problem, groove. Way back to my first subbing experience (which had occurred LONG before the advent of synthetic urine), I was nervous as hell about getting busted subbing as well. I mean nervous to where my hands were shaking like a derelict with a bad case of the DT's. Yet I still pulled it off and thought afterward how easy it was.
My confidence level escalated little by little on each subsequent U/A's, to where by the time the first synthetics hit the scene (almost a decade and a half ago) , I was showing up at the collection site blazed ("brake light" red eyes and all) and grinning from ear to ear. A great feeling it was, knowing that Ive gotten the system by its gizzards. :stoned::stoned:
