Every rural area I've ever worked in had a non trivial number of folks who would have 2-3 drinks at the bar/whatever on a Friday or a Saturday and drive home. It was not alcoholism, it was "I'm totally fine to drive, the law doesn't know my limits" etc.

On some level that's just the price of wanting to go out and not wanting to drop a bunch of cash on a taxi (assuming you can get one to come).
