Can you allow me to goggle for a moment? They expect you to DRIVE to a random drug test? I've never worked in the US (and frankly the idea of my employer having access to my urine without a warrant seems enough reason to be glad of that), but still. If you pass the test, then the whole exercise was one of pointless humiliation, but what if you fail? You were probably breaking the law by driving there.

And why can't you cycle there? If they think there is value taking you away from your work for a blood test why can't you do it in a environmentally friendly way.
