I hope this gets a votey button.
Just on my way out of a company due to gross unprofessionalism from the new GM. My grievances are work related, I believe he is running the company into the ground just weeks in, but i am also shocked by his disregard when it comes to mixing private life with work.
He hired his (much younger) girlfriend without advertising the role, telling anyone it was happening or holding interviews. She is a receptionist, so a big imbalance of power. Today he was hugging her and patting her bottom during a busy time in front of customers and im shocked really, never come across this disregard for any kind of propriety?
My friend says its 'not that bad really' - aibu?? If you visited a business and the older manager was patting the young receptionist on the bottom, you would have a good impression of the company?
My friend does not have a customer facing role which i think shows in this instance 
Bonus gossip - we know he cheats on her regularly, during work hours. Awkward. Im extremely glad to be leaving this utterly toxic boss!! It feels like i slipped back in time to the 70s
