My take was:
1. The people he liked as Managers have moved away.
2. Someone he would have liked to be Manager didn't happen and someone who as less qualified is now his boss.
3. Even though he is qualified, he is getting fewer work hours versus someone who is not.
4. On top he is getting pushed to sell something in a way that he is not comfortable
Ergo, he wants to quit.
But, I agree with you, he needs to have a game plan of what to do in 2017 or better yet, have it lined up before his last day at the current employer.
Wonder, if Samsung girl can help him land a job....hmmmm.....then if he is in a blind spot with her for 30 minutes, I will let you sort out the rest
