I'd be good at that. I can tell the difference between "written or pictorial instructions/information on a board/building/pavement" and a "sign". It's a rare skill
It wouldn't be "key" though, I wouldn't be getting my house repossessed anyway, might just need to cut back on the buckie n ching but could live with it, have done with a greater cut in the past. NEXT! Check me, phure beelin, y0!
