a tram driver?

The husband half of my Thursday night duo told me that when he was in college he had a job as a tram driver. At first I was very skeptical and I thought he was pulling my leg (as he often does), but then the wife confirmed that it was true. He said he often worked the 3rd shift, 10 p.m. to 4 a.m., and at times when he needed money he would work a double shift of 21 hours straight! He laughed about how that would never be possible now ... I don't know, maybe that explains why some of the tram drivers drive so erratically. I swear sometimes it seems like they are trying to hit people.
He also told me a story about one of the funniest things that happened while he was on duty. He said he was driving his tram down Wenceslas Square (Prague's closest equivalent to Times' Square). Apparently the trams used to run the length of the square, but now they just cut across. Anyway, he was part way down the square when he says he had an emergency and he really needed to use the restroom. So he stopped his tram and jumped out. There was a restroom he had planned to use, but it was broken or closed so he had to find another one. The entire adventure ended up taking him 20 minutes, and when he finally got back to his tram he said he'd created quite a traffic jam. There were trams back up all along the square. He also said there were police everywhere and it was chaos.
His story reminded me (in a way) of one of our experiences in Vienna with Jason's parents. We were riding the trams that goes in a ring around the city when the tram just stopped and the driver hopped out. He proceeded to make a call on his cell phone and light up a cigarette. We were pretty confused. Apparently it was time for a 10-minute break. When he was done with his call and his cigarette, he got back in and on we went.
