Back in highschool I needed a new battery for my 1990 Olds. I had recently sprained my wrist and was dreading the install but when I bought it the guy at Autozone said he could install it for free and take the old battery. Sweet!

The kid put it in backwards and popped a bunch of fuses, and since the car had an aftermarket stereo installed form the PO (with very questionable wiring which I’m pretty sure caused more than just the main fuse to blow) it blew that up too.

My “free” battery install cost me $250 all said and done. Oh, did I mention this was on Valentines Day and I had reservations at a fancy restaurant that you need to make literally a year in advanced? Yup. Missed that and they wouldn’t take us for a later time slot and we ended up eating at a Fridays.. Somehow she still married me though...
