Of course I realize that, rationally, but:

* They might feel highly entitled because they paid.

* I feel more anxious to satisfy than I should probably be feeling. Perhaps even guilty for having taken money. I realize that is not a rational frame of mind to be in; it would probably change if that happened frequently. I am used to two things: There is my voluntary work, which I share freely and without expecting money; and there is my 'job' where I have to bow my head to management and do not get to pursue the work as I see fit, and I devote most of my time to - but I get paid (which also kind of happens in the background, i.e. I never see the person who actually pays me). Selling a product or a service is a weird third kind of experience which I'm not used to.
