I don't drink or eat that much by myself, I usually share it with at least one other person, so you don't have to worry about me getting drunk and shooting up the town.
I personally see nothing wrong with washing down a good meal with a glass of suds while strapped, the key term being "a glass" as in one possibly two. But society today frowns on it. And I'd really hate to explain if something were to happen on the way to the car and I had to use my weapon. I would think that a reasonable person with a very low BAL involved in a justifiable incident would be good, but the times we live in...
