First tour in the Navy I went to a "hump" (half-way through a deployment) party and explained to the CO and XO how to better run the squadron. I didn't drink at official command functions after that.

First real job after I got out of the Navy I nearly missed my plane coming back from San Diego - fortunately for me, the people in whose driveway I'd parked my rental car before I passed out went to work early. I always wished I'd known where that was so I could have thanked them properly. I never drank at trade shows after that (but I always managed to take a couple days vacation after I got back).

I don't think there are nearly as many variables as others do. MAYBE if he's very young and it was his first show, blah-blah-blah, you can give him another chance. If it's somebody who's been around the block a few times, or it's somebody you know likes to party - it's either "no shows for you", or "hey, hit the highway."
