Tube Etiquette
After passing through the barriers, one man taps another on the shoulder and passes him a small printed slip of paper, folded precisely in half.
”Push in front of me again and I will cut out your tongue”
He walks on.
A moment later he is tapped on the shoulder by his new acquaintance and handed another small printed piece of paper, folded precisely in half.
”Hand me a pre-written threat again and I will cut out your eyes and fuck the sockets”
He walks on.
