Your mechanic and most of the others will give you an itemized bill, and you can't order him to make you a cup of tea for free. In India and the Middle East this concept of "servitude" is really just slavery - lower class people are basically owned by wealthy families for their entire lives, are are given bare sustenance in return for total control over their labor and time, without conditions or restraint over when and how their labor can be used. Furthermore their work "contracts" actually prevent them from leaving or "quitting", and the legal systems in those countries will actually enforce these contracts and essentially uphold ownership of these "servants" (as did the Indian high court in this case apparently). In all the cases you are describing, the work is part of a regulated labor market, where there are conditions and laws against exploitation, that are actually enforced as has been witnessed in this case.
