This is the best shot I could manage surreptitiously. Train was packed....(again) chap eventually muscles his way into the carriage puts all his stuff on the luggage rack and from his rucksack he takes out a little fishing stool unfolds it and sits down, cue muttering from the other passengers about “sheer genius”..... “very clever” ... and “where can I get one of those?”
I think three were ordered online before we got to Clapham Junction!
