There was a guy who used to wander around Baslow village in Derbyshire, he lived in a ‘cave’ just ff the A619 Chatsworh-Chesterfield road.
He always had a flask with him which I was told, the local village café used to fill it up for him.
If saw him near the village shop, I used to buy him a sandwich. He never actually spoke but did give a nod as an acknowledgement for the gift.
He got a bit of abuse from some car drivers blasting their horn as they past him on the road - don’t get that myself ■■?
He was eventually evicted from his ‘home’ by some newly elected council official (I suspect the ‘Official’ lived locally) and I never saw him after that. 
Sad as, AFAIK, he NEVER caused anybody any bother.
