In the 90s, I went into Blockbuster to get a member card the clerk asked, "Do you have any photo ID?" Because it was handy in my back pocket, I flipped out my passport. The clerk sighed and said, "Do you have any OTHER photo ID?" I balked, "Well, if you wanted a driver's license, why didn't you just ask for that in the first place?!" And I pulled my driver's license out from my wallet. So, apparently my passport is good enough to get me into Russia, Mexico, Morocco, and almost everywhere else in the entire world, but rent a movie at Blockbuster? Hell no. That's serious business.
