One of the most obvious changes I have noticed since returning to live in England after 15 years in Hong Kong is that hardly anybody uses cash anymore, even for the most insignificant of purchases.
This was evident to me on earlier visits to London but the trend has now spread to engulf even the sleepy rural village where I live. Everyone uses contactless payment cards or apps in the convenience store, the café, the pubs, even at the bi-weekly farmers’ market where all stall holders have a mobile card reader. You can still use cash (for the time being) but everyone assumes you will be paying by card. Having to keep bank notes and coins on hand is now seen by business owners as an inconvenience and many actively discourage payment in cash. One of the few places I can still use cash without worry is the chicken farm where I buy eggs.
