Why is it every time I need to get somewhere, we get waylaid by jackassery?

Oh yes, thwarted by Blockbuster again. Like Dr. Venture of whom the quote is taken, I’ve got an arch nemesis that despite (or perhaps because) of their bumbling, manages to take advantage of me at every turn.
I go to the local Blockbuster to rent a game. Not just any game, but BioShock–one of the “most wanted” list that I’ve posted before. Luckily, I find one on the shelf. But when I bring it up to the front desk, the lazy, mumbling clerk asks me if I called ahead. I said no (truthfully). He then goes and checks to see if there are any more. He says there aren’t.
After some questioning, he fesses up that there is one more, but it’s reserved for the guy who called ahead. That’s not standard Blockbuster procedure, but I didn’t want to be a dick and make a scene, since I wanted to come back to his Blockbuster again. So I leave.
When I get home, I two more Blockbusters to see if they have it in stock. One didn’t, but the second one said they had one. We call and ask them to hold it for us until we get there. Ten minutes later when we did get there, it turns out the only copy that they had was for buying, not for renting. Seriously? You’re Blockbuster, and you think someone’s calling you to see if you have any more copies in stock to BUY?! Gimme a break.
End result, no BioShock, but plenty of jackassery.
