Depends on the friends, depends on the family.
Currently working every 2nd Saturday on a friends tree(s) till they are both down. Quite large canyon oaks. Just Rob, me and the HO. He is relatively disabled, so he is limited to what he can do and how much he can afford. He also does a lot for folks that have no one to turn to. Vietnam vet. We trade. He'll come out ahead. Wants to trade me his fishing boat. I don't want a hole in the water to pour money in. So we will be making other arrangements. Again. He'll come out ahead.
Other friend insists on paying me, but I give him a family discount. Again, a guy that really takes care of some folks that cant do for themselves otherwise.
Both these guys donate a lot of time to our local youth as well..
Family, they try to pay. If they succeed, I just spend it back on them

Everybody is a little different.
It's like, I really don't like that bro in law. But I love my sister. SO I gave him a consult for free to tell him what my expert opinion was on his ash tree in Colorado being devoured by beetles. His was about the last one standing in the neighborhood. He had it treated for a few years consecutively. My sister hated the tree.
I showed him some defects and what a threat it would eventually be to the house and how it was crowding out his nicer tree (a bradford pear

) that was quite healthy and vigorous. Not threatening the house. Showed him how to make collar cuts and "thin it" so that maybe the snow "might not" break it.
Sister was happy. Tree gone. Bro offered me a C note. He was happy I refused. I am happy my sister is happy. My opinion of the dude has not changed, but he feels I like him well enough. That is good to keep my sister happy. Hey.... win win...
