Inspired by the plate on a night one thread, have you ever found yourself taking something weird with you?
I was once in a Wimpy Bar with my friend and her budgie in a cage. (We were teenagers, we were on the way back from the vets, it was her idea)
Also I once took half a plastic giraffe almost as tall as me, on the tube. No-one said anything or made eye contact, obviously.
Oh and on the animal theme, once went for lunch from work with a group of friends and friends of friends, one of them was a young man with a pet rat. He thought it was fine to bring it in the Chinese restaurant with us. So he did.
