I went with a friend to a serve-yourself Indian restaurant in North London. I eat Indian food all the time, so I know what it's supposed to taste like. This food didn't look so great, but when we tasted it, it was absolutely vile - every dish was luke-warm, either greasy or watery, with a stale, horrible taste, as if it had been sitting there for days quietly congealing. Neither of us could eat it, so I took the worst looking dish to the proprietor and said, "I'm sorry, but I have to complain about this food. It's completely inedible; in fact it's the worst food I've ever tasted." He just looked at me, took a deep breath and said, "Well - that's YOUR opinion!" and walked away!
