Here's a related situation:
Last summer I measured a course for a new race that a friend was directing for a charity. When I was done w/ the ride, I asked him who I should bill and was told "they don't have money in the budget this year for that, you can bill them next year." I had already made the map but did not submit the paperwork for posting.
The race is coming up next month and someone from the race emailed to complain that they couldn't find their course on the search engine. I replied, "it will be there as soon as I get paid for the measuring I did last year. It's a package deal - measurement, course map, and official certification - you can't pick and choose like a Chinese restaurant menu."
Justified?
