Having done this kind of thing myself for several
years ...
I would submit that if an organization
needs to have several things listed on a receipt for
reimbursement, the onus is on said organization to request such
listings in advance, rather than griping about it
later.
Furthermore, I believe that at least a few prominent
collegiate teams are "unofficial" organizations that do not
necessarily have club offices, etc.
The lesson? Be
Prepared. Know what you need. People are generally
accomodating.
