The Customer is King...

NOT!

Don't get me wrong on this, as each company should always strife to get as much customers as possible and treat them well, otherwise they will not stick around long.

I'm active as free techsupport and customer support for online games, and I'm pretty sure that everyone else who works in a similar branche encounters the same problems.
Users will always try to get on your nerves and demand that they get helped or refunded for things they are not even entitled too.

In worse cases they just demand that you do as they tell because they are paying for your services and demand to be treated like a king because the mantra says "the customer is king".
I agree that we need to help the people, but just jumping at their winks and filling their demands is where I draw line.

This is especially true if they come with problems created by their own stupidity or are telling you how they know things better.
Again, I'm not against helping the people as not everyone can solve problems without guidance or simply lacks the knowledges for doing so, but some people really ought to learn that respect has to go 2 ways.
