Cracking ( literally) not that it's my bag but I'f it was I'd want to have more take than give unlike DM. I shouldn't get into this kinda post when I'm working my way through a bottle of Remy, but suffice it too say that before the law allowed all sorts of pracices that are abhorrent to me a chuffer was a term that meant a Train!
By the way your seats are in my Mum's ( gawd bless her) garden in Cardiff, if you need the number get it off Ian cos she likes him a lot more than she likes me! It's got something to do with him giving her money for services rendered which she was happy to do for free, but I don't think chuffing had anything to do with it, more like Welsh cakes. ( please don't look that up in your dictionary!)
