Did my interview at ORD on Memorial Day. Got a really curt guy, classic immigration-officer surliness. He didn't appreciate my knowing as much as I did. When I asked him about jumping the line at Customs, he was emphatic that it wasn't allowed; after a few seconds he acknowledged (seeing as how I was looking at him with disbelief) that it was allowed at certain airports, but (he claimed) not at ORD.
