Can I also add that as a Scot, I have never eaten anything other than fish or chips from a chippy. Oh - apart from one very drunken night when I had a smoked sausage supper. It did not mix v. well with the half pint of vodka I'd just drunk [barf emoticon]
A good chippy doesn't have their stuff swimming in grease - it has good, crunchy batter. Here we have salt and sauce, which is brown sauce mixed with vinegar, as well as the usual vinegar. MMMMMM....!
