I think you know what I mean, Kevin. If you are drinking, finish your drink, and then go immediately get in your car, that is unacceptable. I don't care if it's 10 drinks or 1.
If you have two drinks at the beginning of a show and the show lasts 2 hours, as long as you don't drink any more you would be fine to drive. I doubt you'd blow a .05 then. http://www.courier-journal.com/article/20130515/NEWS01/130515012/Drunk-How-many-drinks-does-take-reach-0-05-blood-alcohol-level-
If taxis are too expensive, then get a designated driver.
If you're trying to argue with me that lowering the legal blood alcohol level will put me out of work, I have every confidence that people and clubs will adapt to the new law, just like they have with every other law. And if your doomsday prediction comes true and all clubs go out of business, I'll find another line of work. I'd rather drunk people stop killing innocent people on the road.
But I'm certain live music will continue.
