If I'm in a buisnes relationship with them, I surely DO charge them. For my time, and for my costs.
It's crazy that you expect that I wouldn't.

And again, you failed to even notice that you failed to account for externialities.

Just because 1 person dosen't charge you for gettign a thing, dosen't make everything about it free. It would be like you won a free car, and then didn't understand that you pay for gas in it.
