Experiment stopped too soon.
The real application of these devices is the morning after. Am I safe to drive after last night's session? When you are drinking it is fairly trivial to work out/remember if you have drunk enough to be illegal to drive. If you don't know that then it past time you worked it out. Most people here in Scotland where the limits have just dropped have done that.
So do it again but give the previously inebriated hacks the devices to take home to see if they are legal to drive to the office (regardless of whether they do so or take some other transport option).
