Rick? Why is my windshield all oily?
Oh, I changed your wiper fluid and it takes a little while to work itself in.
Huh? I've never heard of that.
Your fluid was empty and I refilled it. That's all.
Uh, what did you use?
Coolant? Coolant. COOLANT?? Can I see the bottle?
* - pause - *
Rick! It says ANTIFREEZE.
Yeah, but it also says Coolant. See?
Either way, Rick, it's WRONG!! That's the stuff for your radiator!
And your windshield. It does both. Honest.
$90.19 later, I had my windshield hoses drained, flushed and refilled... with the correct stuff. At Goodyear. My car no longer squirts radiator fluid onto my windshield.
I wonder why those men were laughing when I drove away...
