We've had to pay cash in pubs a few times lately when card payment systems have crashed. Luckily we have always carried emergency cash for such occasions when out shopping and evenings out as well as for taxis . A few blokes have been raiding their partners handbags for cash to buy their drinks !
As well as the 'normal' bus service , there's a mini bus owned by another bus company that comes round our area picking up as well (only ever us on it, bit scary the first time on my own hoping I hadn't been kidnapped
as it was just plain black with a piece of paper saying 'W6' stuck on the window, but used to it now). One driver couldn't work his hand held machine to get the screen back to visa payments for hubby , after he'd done my bus pass on it, so ended up just giving him cash and no ticket. Probably went into his beer money fund...
