I totally get this, but why? Like, why would he care? We have a weird dislike for hats and jeans (this one still boggles my mind)Then why are you upset? they get free education, food and nowadays $. If I wear a hat in my office I promise you my boss will tell me to take it off.
Like, if you had a hat on at work, would you be a bad worker-bee all of a sudden?
