Just say your popping to the shops for a pint of milk....
We collect for Grace House Hospice whenever we do any charity events:
http://www.gracehouse.co.uk/appeal_theneed.htmlThe way we usually do this is to charge £30 per car and ask that the car owner then gives what they want by putting it in the charity collection box. Once our costs are covered (wages, cost of running dyno etc...) the profits all go to charity.
Our costs are the same wether its 10 cars or 30 cars so the more that come, more goes to the Hospice.
Someone make a list of names, if numbers are low then I will open it up to another forum (of our choice) to mix it up and make it a little more interesting.
