His BAC was at .18, that isn't sober by any means, but not shit faced drunk either, especially for an alcoholic.
I have spent a ton of my life on the road, in my early life I was a traveling salesman, so for several years I had as many hotel nights as I did in my own bed. On the road you spend a lot of time in bars, a lot.
Somehow I never was kicked out of one, asked to leave, or caused any type of problem, other than probably being to loud, and I don't remember any of the other people in the pub getting escorted out ever either.
Side note, I likely could've retired in the next couple years, for the amount of money that went into a few beers/whiskeys, and the black jack table.
Guy has a ton more going on than being a lousy drunk.
