So I was halfway done with a Triple Cheeseburger. I was eating it in the Subway, and I dropped it on the floor. I think it was on the floor for a maximum of 5 seconds before I picked it up, and it looked like the burger touched the floor, but not the whole burger, cause part of it was still in the wrapper. There was no one else in the train but this old lady reading a paper or something and I don't think she noticed, so I think I did the right thing by finishing that burger, right? There wasn't any noticeable dirt or crap on it, and the train didn't look that dirty.
