In reply to Andy Long:
Difference is he can work all day, then climb to 10pm at night, on an ever changing selection of sport lead routes, pre-placed top ropes and boulder problems, ranging from smooth slabs to steeply overhanging competition walls. At the end of it, an array of pubs awaits and probably a short ride home again. Not to mention a London wage (being in London, he's probably a banker and on 50k+) that makes outdoor climbing in exotic locations all the more accessable.
Same can't be said for much of the UK outside of London, so perhaps £40+ isn't so bad.
