EH shopping trip with her husband didn't really shed a good light on him and made him look kind of like a baby. I would have been pissed if my husband did that to me, but then that's why he doesn't go shopping with me.
Even if he did go shopping with me and tried to pull 'the line is too long' whiny crap I would have told him to either suck it up or go sit in the car while I waited in line. I would not have done all that shopping just to leave a full cart because my husband was being a baby.
I'm pretty surprised that EH gave in so easily to him she seems, on the show anyway, to voice her opinion/objections/dislike very easily. Why appease a grown man?
