Put a string on it...!?

Today I have decided to have a mini rant... what is up with fully grown human beings wearing their oyster card on a string around their neck!? It annoys me beyond belief! Especially when they hit you with it, scratch you with it then catch it on you ... turn around and give you a dirty look - as if it's my fault they need their crap on a a string because they're too stoopid to look after it!!? Yes obvs you can guess this is aimed at someone who will probably never see this but too the freckly lady with the glasses and purple lipstick on the victoria line.. you have been told! The only thing your allowed on a string are some cute ..no... very cute wollen mittens in your coat! that is all...
