I don't think it's subconscious at all. If, for instance, you contract something on fiverr for $5, you expect $5 of work. If you contract something for $1000 you expect $1000 of work. And the former's probably going to take a lot more feedback to get to where you want than the latter.
Basically, you get what you pay for. That's not always true, but it holds pretty reliably.
