I've been going to business meeting for the last 20 years. I've seen it more than a few times, and have done it myself. It's done to men or women, before the start of a meeting when someone enters while others are seated. It's the equivlalent of a hello to someone you know well. Nothing more, nothing less. If you watch the video, he did not stand there rubbing her neck. he gave her a squeeze hello.
Not only appropriate, but relatively common. Her reaction was what made it comical.
ANY excuse to Bash....
Even if he did massage her shoulders a bit, it was simply a kind gesture.
I've also been in professional settings where this is not considered inappropriate.
OMG
Almost fell off my chair!
A voice of reason...
