Not suprising for the nouveau riche. My buddies and I have witness acts like this so often, we nick-named it the "tude", as in attitude.
From the asshole that parks his Hummer sideways in 2 handicap spots to stupid brats that trash resturants and laugh at the staff, it's really stupid behavior. The "old money" knows better than this and mostly stays off the radar of the rest of the public.
