My personal exposure has been pretty limited but I have friends who get it a lot :/

I can see that being a real challenge for fic commissions. I've only ever commissioned friends who were in a financial spot and thus I knew, like, what I was getting and that the person had knowledge of what I like and had reason other than money to make me nice things (not that money isn't a substantial motivator but like....I guess I'm saying the personal connection part was important).
