Reminds me of an incident I had at EDI last year. A woman at customs who was completely out of order gave a few blinders during our short but heated exchange. My favourite:
Idiot: What was your first point of departure today?
Me: Kiev.
Idiot: What was the purpose of your visit to Russia?
Me: Kiev is in Ukraine, actually.
Idiot: Let's not split hairs.
Wonderful considering Scots would be the first people to be outraged if someone claimed Edinburgh was in "England", and someone else said "let's not split hairs".
