Ouch!!!
The worst thing I ever had happened in My shop back in the day was a Rolls-Royce Silver Shadow engine fire.
Worse was the clean up of the fire extinguisher mess.
Fortunately, we didn’t skip or skimp on insurance like a lot of small businesses do and it was tempting in the early, hungry years.
The silver lining is that the fire saved our roof because the heat and smoke killed killed a termite colony in the roof we didn’t know about. Buggers were falling out all over after it was out. We sprayed anyway, but the guy said he was pretty sure there were no survivors. Rest of the building is brick and concrete.
