Hannah has had a tiring day at the office and is now on her way home.
She gets on a tube train at Bank station and, as usual, is dismayed to find it packed.
Everyone is squashed together like sardines. But this time, things get worse.
During the next 10 minutes, she becomes more and more aware of the man standing behind her - so much so that when the train reaches Euston, she turns to him and without attracting other passengers’ attention, says, "I can feel something hard rubbing against my backside. Please remove it."
The man quietly replies, "There’s no need to get panicky. I got paid today and what you feel is a roll of £50 notes in my pocket."
"So are you telling me that between Bank and Euston your salary doubled?" says Hannah.
