Cashless payment system needs tweaking

Sometimes I feel like I belong in the last century.

When I worked in London I was the last person in my office to get a cellphone, I prefer talking to people face to face rather than sending SMS messages, and I still have a good old-fashioned desktop computer rather than a nice portable laptop or tablet.

Until recently I was one of those people waiting in line at shops who was always grumbling when another customer was using cashless payment, wondering to myself why they couldn't just use good old-fashioned cash, especially when the payment had some complications and was taking longer than normal.
