"They make the choice, but claim it's their spouse's decision, to prevent having to explain their decision."
Children are another excellent example, I'd have to put up with an enormous level of extra B.S. in my life if I didn't have kids. "Oh you scheduled an all weekend teambuilding event on the other side of the state? soooo sorry I can't go, who would watch my kids all weekend?" "Whoops the company picnic is on Saturday, thats just too bad we have a soccer game" "I'd love to stay late to attend the diversity committee meeting but I have to pick up my kids at the library minecraft club meeting" "Oh the team is drinking until they vomit and then seeing who gets a drunk driving ticket? Wow that really sounds like fun, but the kids have a scouts meeting tonight and I'm the treasurer and in the leadership committee so I'll just see you guys tomorrow...". Back when I was single and childless I had to participate in all those idiotic primate dominance rituals, but having kids is a get out of jail free card preventing people from screwing around with my private life to prove they're superior enough to me to get away with it. Screw those bastards.
I suspect the business types know exactly whats going on and just don't want to make a scene.
