Yes, I realise that. I was curious to see if people offer things that would be just between us, just like it's between me and my camp that they offer me access to a basic kitchen and a nice camping place. But that would be paid in advance to avoid the nastiness of cash exchanges occurring during the week.
BM isn't commercial, but there are exceptions. Ice and coffee are one, entrance to particular camps are another, and I was just wondering if there are others. I don't think it's an unreasonable question

I realise that it won't be governed officially by BM, the same way camp entrances aren't.
I don't need anything in particular. I did fine with my basic supplies (I didn't bring any food at all for my first burn and used nothing but Irish charm to eat for free all week), but this point has been on my mind.
