I am not surprised by this. When I was at Newark the conversation with immigration guy was something like this:

Him: What do you do? Me: I am an entepreneur.

Him: Haha, ... we are all entepreneurs, now really, what do you do? Me: Websites

Him: I've heard there is a Sillicone Valley in Russia and they want to take over that ours. Me: Um, okay. (I am from Czech Republic)
