Oh, come ON....

So. This morning, I took Harold the Hoopty Car up to Hoffman's Car Wash and Jiffy Lube Center for an oil change, where the following conversation took place:

Friendly Mechanic Guy with a Clipboard [F.M.G.w.a.C.]: You're here for an oil change?
Me: Yep. [turns off engine]
F.M.G.w.a.C.: Have you been with us before?
Me: Yes, I have.
F.M.G.w.a.C.: [jots down on clipboard] What's your current mileage?
Me: Ahh, crud, hang on.... [starts engine again]
Harold the Hoopty Car [H.t.H.C.]: Vrroooooooommm....
Me: It looks like 57,263. [turns off engine again]
F.M.G.w.a.C.: 57,263.... [jot jot jot] Alllrighty, you're all set. Have a seat in the waiting room, and we'll give you a holler.
Me: Thanks! [starts to exit car, realizes that the window's still open, and it's snowing] Argh. Hang on, let me get this rolled up. [turns key]
H.t.H.C.: Vruhh. Mff. *click*click*click*
Me: Uh-oh.
H.t.H.C.: *clickety*click*click*
F.M.G.w.a.C.: Sounds like you've got a bad battery.
Me: Um.
H.t.H.C.: *crickets chirping*

Okay, I'm trying to look at the positives here: if your battery is going to bite the proverbial wax tadpole, you can hardly pick a better spot for it to do so than right at the main gates of a shop where they sell, install and service batteries. Still, not exactly the sort of additional purchase I was looking for at this exact moment. Gahh.
