A friend of mine parked his work truck at a train station, and took the train to the ballgame while on company time. While he was there, he ran into one of my company’s engineers, who was also skipping work. they nodded to each other.
The engineer then high-tailed it back to his office, signed himself out for part of the day, and called my friend’s boss to rat him out. What a dick.
To answer your question (I sometimes get around to that), I would be too nervous not being where I was supposed to be. I have done similar things in the past, and just couldn’t get into them, knowing I was playing with my carreer.
