I work in a bookmakers and have seen over the years a decline in people coming in and placing bets, it's all being done online with many enticements so people do all their betting online, those that do come into the shop can pay with their money in the online account and winnings go back into the account so no money actually changes hands at all.
Most days there is more money put into the machines via debit cards than there is in cash - again with any winnings going back to their cards.
As a business we are cash poor, something not many people realise, and I am sure if you look at other leisure companies you will see the same story over and over
