To be clear, I assume she was just joking around, as I would have been had I said what I was going to say. But neither is appropriate. And the man is more at risk when he says such things.

Why is “neither appropriate?” There used to be a day when people could chide or tease their coworkers and everyone laughed. The political correctness has spread so far over our culture it will ultimately destroy everything. What is the cost of a smile or laughter? Must we be confined to being serious all the time? Critical of everything and everyone? I’m an old woman but if I see a man with a handsome mustache in the grocery store, young or old, I often say “Love your mustache” as I pass by. It has brought many a smile to a serious face and I only hope the message lingers a little while. When a young man or an old man holds a door open for me, I make sure he knows how much I appreciate it. In addition to “thank you” I tag on a comment like “so nice to know there are still gallant gentlemen in this crazy world.” I always get a response and a smile. Little touches of kindness or happiness don’t cost much.
In my case, my wife would not appreciate it. From either side.
But yes, the political correctness part is as you say.
