Recontextualize this for a minute and let me see if it still makes sense. The company offers a salary of $50/hour when he thinks his market rate is $100/hour.

Recontextualize this for a minute and let me see if it still makes sense. The company offers a salary of $50/hour when he thinks his market rate is $100/hour. He refuses, countering by asking for $100. The company comes up to $60. He refuses. The company makes the following final offer: "OK, you win. We'll pay you $100 per 1 hour 40 minutes and you can work as much as you want." How have they bettered their offer? Especially when there are (presumably) other market rate jobs out there.
