Why do so many people expect you to do things for free? What hides behind this mentality?

I have been managing several communities and doing marketing for over 3 or 4 years, and I have noticed a pattern where about 80% of people "test" you to see if you will do things for them for free.

I also notice that people from certain countries tend to do this more often. For example, Central and Eastern Europe + Southeast Asia.

On the contrary, people from the USA and China are willing to pay.
