Anyone been banned from a curry house (the cheap'n'cheerful type where you get chapatis thrown in for free)? Quite an achievement, I believe, they generally want to keep the business and are adept at coping with a bit of disorder.
Several of my student friends managed it, in Bradford. They'd been urged by a (Pakistani) fellow-student to ask for
<some obscure word in Urdu>. Not having a clue, they duly asked for it several times, each time being told that "it wasn't on the menu today". Finally, they struck lucky. What it was turned out to be some sort of curried calves-feet concoction. They protested that it was totally inedible, refused to eat it, made one unholy fuss, refused to pay and were then thrown out. I wasn't involved since I wasn't there at the time

. So I kept on going to the place (it was a good curry-house) and no-one complained. Whether the Pakistani student also got banned, I do not know...
