It does happen now and then - Last weekend Peterlee DZ near Newcastle hired me and 2 of my mates as FS coaches to go up there for a coaching weekend. They paid our petrol expenses and food and lodgings AND were intending to pay our slots for the first couple of FS coaching levels for their low experience jumpers.. AND we were going to wear video cameras.. Unfortunately the Great British weather kept us on the ground - but the plan is to try again later in the summer. - So whilst I appreciate your point - it is as rare as hen's teeth - but just occasionally..........
