Several times recently I have been standing in a queue at the bank and witnessed very frail elderly people withdrawing large sums of cash. In each case the customer has announced very loudly the amount they are withdrawing and the cashier has counted it out conspicuously before shoving it across to them. I was very alarmed at this as I thought it would make them vulnerable to mugging. Is there not a way that cash could be handed over more discreetly in banks?
