I turned up to fly some freight one night and they said "Right Onan, you've been selected for a random drug test. Here's the paperwork, the place is out on 183."
"Oh, ok" says I "what do I do? Call 'em up and make an appointment?"
"Well if you do that" she replied, an edge to her voice "it won't really be random now would it?"
Here is a picture of her telling me this ===>
btw, I passed the random drug test, even though I had to guess at two of them.
