Out of all the immigration officials you deal with when entering the US (i.e. not in the back room, but those presenting a "face" for the country), such an incredibly large amount are such toolbags. They have no manners, show no respect, nothing. It's not all of them of course, but far more than is acceptable. I don't know how to put it any other way. They are simply power-tripping losers. It's frankly embarrassing for the country.
