'Go For an English [sketch title] - Goodness Gracious Me [long-running UK TV series]'
In the UK, especially amongst students and in the few years that follow student life, going for a Friday night curry [aka 'cuzzer', easier to say when drunk I suppose
] is a social institution and something of a right of passage.
The typical night is going to a pub after studies or work, meeting your mates, getting several beers in you, then leaving the pub early enough so you've time at the restaurant, and aren't so drunk that you can still walk a few hundred metres.
Once there, you'd normally order poppadoms with the pickle-tray for the table, while choosing your meal. To many young Brits, especially from rural areas, going to a 'real Indian restaurant' (that's BrIndian curry of course. And in an Indian restaurant everything on the menu is considered to be 'curry'
). Choosing the meal takes time as the menus are long, and the newbie has little idea what anything is, so that's time to order some more beers in in the interim. Since everyone is likely drunk already there can be a bit of 'banter' [jokey chat] with the waiters, and very occasionally they'll give it back too. That's when a drunk and 'wound-too-tight' diner can get angry. That said, I have never witnessed violence or even the threat of it in an Indian restaurant (whereas I have in budget 'Chinese' places in London's Chinatown).
Choosing the food is a bit of a maze. Some people don't want anything spicy [aka 'hot'] at all. Others want to show their bravado by ordering the hottest thing they think they can probably handle. It is ironic that back in my student days even a mid-level spicy dish like a chicken Madras was spicier than anything I had had immediately previously during 3 months in India. [I thought the food in India would be nuclear-spicy, and was very surprised to find it almost bland compared to BrIndian food
Anyway, the sketch is going to be intuitive to any Brit, but likely less so to others hence the above. The sketch is a cleverly observed reverse-parody of a group of young Indians going for their regular 'Friday night English' in Bombay.
