A lot of my friends on FB thought this was really funny, but I didn't. I'm sorry, but even though there is no excuse for physical violence, he riled her to that point. I've been sitting behind a constant complainer before and it is irritating when everyone's in the same boat, but no way would I ever resort to retaliatory rudeness. In fact I'm unsure as to whether it even is retaliatory rudeness as she didn't show rudeness to him in particular, she was frustrated at the situation and didn't handle it well.
As to whether it was this woman's last Thanksgiving or not, I'm unsure as to whether to believe that. It seems somewhat farfetched but maybe I am cynical!
