To me it doesn't really look like the husband was trying to protect his wife, it looks more like he was trying to catch the home run. I also don't think the dumping of beer is the big story here. Her first reaction was to immediately retaliate, no hesitation. To me that seems like anger issues and I would be willing to bet that this isn't the first time he's felt her wrath. They are all laughs and smiles now but when they get home, it's all business. Angry business.
