imo, it's first-come, first-serve. Of course whoever needs it more should get precedence, but that's up to whoever got there first to decide. Usually if I see someone else heading to farm a ginormous wave of minions that I was heading towards myself, I'll just let them have it. The time I have an issue is when somebody comes in to "help me clear them out" when I'm playing a decent farmer and completely decimate the wave by themselves. I don't play carries much, though, so it doesn't matter as much. Normally if I'm underfed I'll just focus more on jungling later game; it's safer, and your jungler should understand (and may be happy for some lane farm).
