IPF's WTF thread reminded me of this "woman" who graced me with her presence a couple of weeks back.
Me: Can I help you?
HB: Yes I need wiper blades for my 2006 Honda Accord.
Me: I think you want the building next door. They're Honda. We're Chevrolet.
HB: This isn't Honda?
Me: No ma'am.
HB: HOW THE FUCK WAS I SUPPOSED TO KNOW? FUCK YOU! <leaves>
CW: <said to the slammed door>Oh, I don't know bitch. Maybe the BIG FUCKING SIGN OUT FRONT?
Then we laughed a lot.
