Having heard and read more and more about these "walk in and blow" tests, I have decided for myself that I will refuse it should it happen to me.
I am sick and tired of being criminalized and put under a general suspicion without anything indicating any fault on my side.
I am being security screened every damn time I enter my workplace so I don't hijack myself with my swiss army knife, and now I am being placed under the general assumption to be drunk at work, and they make ME prove MY OWN INNOCENCE!
In any civilized country the proof of burden is on the governments side, not on the subject's. This is going way too far, and as I have said, I will refuse the test if the police cannot give me any reason on why they would suspect me of being drunk. If I stumpled around doing the outsidecheck, fine, if they claim to smell booze on my breath, fine, but no way in hell am I going to give in for no reason at all.
