I couldn't help but smile at this...

A friend of mine just shared this video, which is too good for me not to share it further.

It's humorous but makes some serious points about client / vendor relationships.

Watch, smile wryly, and then think about when you are either being unfair in what you are asking for or where you are perhaps under-valuing your services.  I recently read about Belgian ad agencies staging a week long virtual strike in protest over the way pitches were being run.  Worth a read.
