To the dinosaurs like me, a Bluetooth headphone is just another headache. We need to charge it or check if it is fully charged. Or discover that we have forgotten how to connect the ancient Bluetooth device to the next smartphone. Or vice versa because the rechargeable battery in the Bluetooth device has died.
We got used to the wired earphones and the Bluetooth device is a tradeoff we do not want. Or a habit that we just cannot pick up.
It is the same with the QR menu. Or using cash. It is a dealbreaker to some people because we are learning things instead of having fun or having lunch.
Or even worse, having to depend on the younger generation to assist us for a task we never had issues with the past.
