Shanghaiceltic, is that in Shanghai, the restaurant receipts?

Ethereal Purple, thanks very much - it would be great to have more information about the scheme. For something I'm writing. You're really good to offer to go to the trouble of finding out about it.

And anyone else who knows about similar schemes - where people are reinforced for doing stuff, rather than punished for *not* doing it - please add your information, if you'd be so good.

I'm also looking for information on an English (I think) city that was having problems with street-fighting. Some of the dance venues got together in one area and agreed to play slow music for the last few sets. In that area the violence and street fighting sank back to nothing.

A friend told me about this around six months ago - think she'd heard about it on the radio, but I'm not sure; now she says no, 'twasn't her. Anyone know about this?
