I remember once when i was waiting for a train. And when the Train reach all the carts was empty except for ONE.

So when i walked in and the door closed all i smell is some SUPER NASTY smell as if some one used the Bathroom all over the cart. Only to notice it was only one stink Homeless man in there.

I switched carts next stop. The funny thing is every stop the Train Conductor and passengers would warn people not to go in that cart...sometimes they don't listen...

.But as soon as they reach the next stop they run into the next cart saying. OH I GET IT NOW.
