Recently I was on the subway and train stopped at station due to medical emergency. Engineer said they called ambulance but it would be a few minutes until they got there. 

I got off, went down stairs to the express train heading same direction , took it past where I was going to dinner, and then got off and got on the original train line heading opposite way back into the station I was originally going to. I was very proud of all this cleverness. When I got to be restaurant I had to wait a half hour anyway because everyone else was stuck waiting behind the train with medical emergency. 

What do you say about that
