Unfortunately give someone a little bit of authority & they want to be the 'big I am'. I do not drink & fly, that is thoroughly unproffesional. However prior to a 12 hour trip, I do not think it is condusive to flight safety to be subjected to almost ritual humiliation by being forced to undergo breath testing infront of the passengers. By all means test, but not infront of passengers who may already be extremely nervous about their forthcoming flight. For the most part we are professionals and should still be treated as such. When we get airborne our minds should be on the job at hand, not on how we have been treated as criminals on the way to the gate. The press would have the public believe that we are all alcoholics, that is not the case.
