You can still decide its not worth it as a volunteer, more reasons to.
Pro rugby has already let the complain/moan cat out of the bag, scaled reward commensurate with operating level is the way forward.
The notion that both clubs shouldn't contribute for the services officials is outdated and proliferated by those who espouse the volunteer workforce 'great con' if grassroots players all paid £1 each ( the price of a packet of crisps in most pubs) then none of them would leave the sport citing cost.
The wealthy volunteer minded refs could donate their fee into a pot called "Ref PR dept" to be used to promote/recruit/train referees, or give it back to the clubs that respect and host them best, if they wish.
The mega millions involved in rugby require a mindset change towards grassroots officiating IMO.
