It’s no different from petrol stations though??
My local asda unmanned petrol stations has a button for disabled assistance, as does most stations.
If you are having problems ask! I saw one guy couldn’t get the ev plug out of his car and 3 people stopped to help, he never asked him, they just went and helped.
There is common sense and some people just pick nonsense and run with it.
If you have trouble at a petrol station or an EV charger, people will come and help you.
