Drinking and driving is bad

Rico says his friend Tex sends this admonitory story:

I'd like to share an experience with you about drinking and driving. As you well know, some of us have been known to have had brushes with the authorities on our way home from the odd social session over the years. (Not me, of course.) A couple of nights ago, I was out for a few drinks with some friends, just a few, at the Marriott Hotel San Jose and had a few too many beers and some rather nice red wine.Knowing full well I may have been slightly over the limit, I did something I've never done before: I took a bus home. Sure enough, I passed a police road block, but as it was a bus, they waved it past. I arrived home safely without incident, which was a real surprise; as I have never driven a bus before and am not sure where I got it.
