I knew chuck curcio very well when he had 2 stores I Wpb. Got him his first loan for equipment, when I was in the businessBack in the 90s, I was a store manager for a chain in Florida called Tire Kingdom. We never charged for a flat repair and always patched, never plugged them. I always told the customer it was really easy to do and if the tire wasn’t on the car, it could be done in about 15 mins. I would always ask them to take care of the tire buster for his time and they normally tipped $20.
