You must have me confused with someone else because I didn't say that. I just said it was inappropriate, mainly because of the setting. You just don't do that in the business world.
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.
Actually it does more often than not and no one complains except folks like you. Fortunately you are in a really, really, really vast minority..........
