I have visited both of the elderly ladies in question just now who were having lunch together and have put your views to them. With regards to the purchase of train tickets, they are both of the opinion that the railway station booking office at Wilmslow station had catered for their train travel years for a great number of years where the member of staff did all the work involved in producing train journey tickets which allowed for the price discount of their Senior Citizen Railcards. For which they then paid cash. Both these two ladies have no living relatives who could purchase train tickets on their behalf and if the only option for obtaining rail tickets, was the use of machines, rail travel would become a thing of the past for both of them.
One, a former headmistress, more vociferous than the other, said the onset of onus on customers in retail supermarkets to do the work of employees at self-checkouts was a sad reflection on society today. She had impressed that feeling very strongly to the store manager of the local Waitrose supermarket. She despaired on hearing that railway booking offices might well soon be a thing of the past and said it was a sign of the times when "the younger element" just blindly accepted the whims of multi-national companies into accepting the use of smart phones and the associated annual costs involved in telephony packages from companies such as EE, Tesco.etc.
I believe the phrase for that is "cutting off your nose to spite your face", or alternatively "curmudgeonliness", and I have little sympathy for it. Sure, they might prefer to use the booking office, but why do something as silly as reduce the travel you enjoy because you have to press a few buttons on a screen?
The reason "the younger element" (I'm 43) "accept" the use of smartphones is because they enhance our lives by providing great convenience. Perhaps if they tried one they'd love it. Again I'd recommend Apple kit for simplicity for non-techie people - a lot of such people have very bad experiences with budget Android phones and tablets and are put off that way. It costs more, but there's a decent used and refurbished market.
And I also
prefer self-checkout. They allow more capacity in smaller space and there's not the pressure to "keep up" with the checkout operator in packing your bags, so you can spend the time to pack them in a sensible order and save time on arriving home. They sometimes are additional, anyway, providing greater convenience by shortening the queue even for those who don't want to use them* - my local Co-op has two self checkouts and two staffed tills, when previously it only had two staffed tills.
* Whining about "why did they build the M6 Toll, I would never pay to go on that" is similar - it improved the situation in Birmingham by taking traffic away from there, so even benefits the people who
don't use it. HS2 is similar with regard to the south WCML.
