I don't agree with you saying the CC should have put your wife's bag away TG. CC have plenty of other things to do, and stowing pax bags is not one of them. What if 100 pax couldn't stow their overhead bag - should the CC be doing all of those? You then complain about other pax not helping - so what is your actual complaint? CC who's job is NOT stowing bags, other pax (who I wouldn't rely on at all), or the fact that you were late boarding and got grumped at by your wife?
I would have thought those on staff travel would take every step to make their co-worker's day that little bit easier, rather than whinge about them.
