I figured the jig was up. The device registered 0.07. Being impaired from the drink and compounded by the my nervous floundering from just the situation I found myself in, I could barely talk. After debating my plight, they let me go. They told me to stop at the nearby bowling alley, spend some time, and drink some coffee which I did.
Life is simply too short for such aggravations.
The options are obvious. Car pool with somebody acting as the designated driver. Take a cab. When possible, spend the night in the guest room. For the cost of the round trip cab fare, I had peace of mind.
