“When the coins are inserted, the banking poster falls to reveal the fruit machine ‘gambling’ display. The bankers pop up out of the holes in the table and the game is simply to whack as many as possible in 30 seconds with the investment instrument (the mallet). There is an easy option, ‘low yield, safe investment’ and a much harder one, ‘ high yield, high risk investment’. If you lose, the bankers put the experience behind them and return to business as usual, If you win, the bankers retire and thank you for funding their pensions.”
