Better Service than AAA
One of the most important skills you can have as a motorist is knowing how to change a flat tire. It’s both easy and difficult at the same time. First, you need to jack the car up, then remove the lug nuts to detach the wheel, and so on. But if you encounter a real-life guardian angel, then all your problems are over.
But the guardian angel didn’t just swap out the flat tire. They also recommended a good mechanic to get their car checked. And if that wasn’t enough, the OP learned that the guy visited that exact shop earlier and paid for the replacement tire.
