So, hot day on the Tube, most but not all seats taken, nobody standing, so good lines of sight.
Young woman gets on, scratching her arms and legs. So far so good. Then she unbuttons her blouse, pulls her left breast out of her bra, has a good scratch, puts it back in her bra, pulls out her right breast, repeats the performance, and buttons up her blouse.
But this is England and nobody bats an eyelid and nobody says a word even after she gets out at the next station.
I can only speak for myself but I thought This is a hidden-camera show and I am not going to be the one who makes a tit of himself on television - and perhaps I was right although I never saw the broadcast if I was. Of course the producer might have decided the clip was a failure and not used it precisely because nobody reacted!
