The Delhi variation on this well-known trick is particularly nasty.
If a shoeshine man should happen to spring up from nowhere and point out the sudden appearance of a nasty gobbet of ... poo on your shoe, don't be fooled. Stuff doesn't just appear on top of your shoe - that's against the laws of physics - if you'd stepped in something it would be underneath, wouldn't it?
Yes, the scam artist put it there himself while you weren't looking and will try to extract a hefty fee from you while making a big fuss about sorting it out. Be hard and don't pay any more than the going rate - 10 to 20Rs or so.
Especially around Connaught Place and other touristy spots
