I think at the moment people need to be careful demanding too much from the development because right now it's not making any money (it's not even built yet) you don't want to jepordise the whole thing. Tesco, however, is a huge company which can afford to give out almost infinite amounts of cash (£3.4bn profit last year). I can't remember what Les said at the planning committee but it was something about not being able to stipulate planning conditions in order to profit from a local development.
On a related note about money for the PC. Perhaps something to bring up at a future meeting is to apply for some funding from the BIG Lottery fund. You can get from £300 up to £10k for community projects such as protecting the wildlife in a local area or improving a community hall/space for example.
