That's a good point, it is another form of dumbing down.
How about this instead:
Punter: 'Excuse me Mister DJ, would you perhaps have (insert random tune name here) that you could play for me and my friends, it's one of our favourites and we'd love to hear it, it would really add to the enjoyment of our night, for which we've paid seven pounds entrance fee'?
DJ Warwick Hunt: No, sorry.
Does remind me of a story Jo told me once. Some misery at These old shoes, so she goes up to him and the conversation goes:
Jo "What's up, you look really miserable?"
Misery: "I paid £3 to come in here"
Jo: "Oh really, well here's your £3 back, now drink up and F8ck off"
