In my experience, this also applies to cheap vs expensive projects (consultancy). Customers start to get really pleasant and polite when they are charged at least 100K or something like that for doing some custom software development. They get very demanding when it's below 10K.

Might be because you're talking to different sets of customers. People who are cheap vs people who know what they want is complex and are willing to pay for it.
