I don't donate much the odd penny maybe when I buy a Mac D's or something but in general I prefer doing something fund raising once I did a 9 hour sponsored silence (A full shift in my place of work) where I couldn't speak to ANYONE including customers, my boss or anything so I had a piece of paper and a pen to write what I couldn't put in to actions and mime out. I had to operate a checkout in that state too I was forever gesturing things and spinning the screen for people to read the popup boxes. This year me and a friend wanted to do a wheelchair race dressed up around the carpark he was going to do a ballerina whilst I did a big dog or gorilla suit we'd have paid for the hire of the outfits but the store manager said no because of the fact he thought we'd be seen as "taking the pee" out of disabled people.
