Now this I do know for a fact - OSHA does NOT test as often as they should...and in alot of instances, they give notice as to when they test (not OSHA per say, but the site bosses). If he's a heavy machine operator (Crane Operator), then chances are he works very long hours and needs something to stay awake and keep his senses keen. I'm not really leaning towards him being a drug user still, but it would fit his "profile". There's a reason why M waited to call 911. I could have been 12 babysitting and would have called 911 immediately! No matter what kind of scenario we all come up with, nothing can make sense as to why this chick didn't call 911 right away...nothing at all.
