Have you come across 'fund raising' companies like Speedmark coming to schools, and wanting parents to get sponsorship for their kids to kick a football 3 times in a net - and then the school only gets to keep 50% of the money raised.
I know they have costs to cover but 50% seems way too much for the company to keep, however nice a day the kids have. The website says they've raised over 2 million so far. A nice little earner.
