Need a Taxi?

I was recently out for an evening with friends and had more than several beers, followed by a couple of bottles of red wine and then a few vodka shots. Although relaxed, I still had the common sense to know I was just slightly over the limit. That's when I did something I've never done before: I took a taxi. On the way home, there was a police roadblock. But since it was a taxi, they waved it past, and I arrived safely home without incident. This was a real surprise to me. Why? Well, because I had never driven a taxi before.
