Most batteries can handle one or two hard discharges in their life (Drained to 9.5 volts) and have a 50/50% chance of coming back to full charge and hold. Other crap out and NEVER come back again.

Most shops pull the battery posts loose, but I would bet as this one is the trunk under 2 ft of stuff, they never opened the trunk. One or jump starts and off it went over the curb never to darken their doors again.....
