I was on the tube the other day and a fairly old woman sat next to me (good job that the seat next to me was free because I wasn't going to offer her my seat) and she did look fairly odd. She smelt a bit like tinkle also. She had a horrible reusable carrier bag and I could see what was in it. She had a can of Spam and a pretty big twig. That was it. Maybe she was going to eat the meat from the can with the stick? She seemed like the kind of person who wouldn't own a fork.
So what is the oddest thing you have seen in a bag that wasn't yours?
PS - I would have really stood up and offered my seat if there wasn't any available.
