The notion of service has changed as technology evolves. We’re now much more comfortable using AI-powered smart assistants; everything from satnav to Alexa and Siri to fridges that tell us when we’re running low on milk, all there to take care of mundane tasks and make our lives easier. But we still love good, old-fashioned service that you can only get from human interactions – the person who remembers your name and favourite coffee order in your local cafe, or a beaming smile and extra snack from the cabin crew on a long flight.
