Haven't lived there for fifteen years, Cowfold. Just never changed the user name. I confess I thought it was quite posh even when I lived there, though - it was all doctors and the like resident there at the time.
I'm not sure I'd describe my list as 'upmarket' though - surely that's a label...
Salt and vinegar Discos for me. Or original Hula Hoops. Quite partial to Sour Cream and Onion Pringles too - the only acceptable flavour of that brand. Those spirally ones, too - Twisters, maybe? Them's good eating.
This is making me all nostalgic 'coz I almost never eat crisps any more.
