Re: Fat chance
Amen! Every year or so I slope into M&S to buy some bog-standard cheap black trousers for work. It's got to the point where I'm highly unlikely to actually find anything with a 30" waist on ther shop floor. So I usually end up muttering something about the vast majority of GB being fat bastards and then try and order online where they may be more choice.
On a similar note once upon a time I could have sworn I was size medium for most things (I'm 5'10", albeit thin as a rake), but now I seem to be size small. Now I don't think I've shrunk at all...
