I know of the chap - he is always polite to me but I've seen him be quite irritated at the traffic at the out of sequence crossing outside FH station. Good on him.

Incidentally, what ever happened to that chap from about 8 years ago who looked like wurzel?
Clearly he used to sleep rough in the doorways around FH.
Looked about 1ooyrs old, with a large matted grey beard and, how do you put this politely...
you knew he was around from quite a distance....

Very quiet and polite.
Very distinctive and very vulnerable.
Probably moved out when FH started going down the drain, but I really hope he found help.
