Having breakdown cover is essential if you own a car that you actually want to drive somewhere. Cars break down and we have places to be, so being able to call a tow truck is incredibly useful. For example, you might drive over a nail and not have a spare tire.
But then the tow truck might arrive and drive over the same nail, and not have a spare tire. So what does it have to do? Why, call a bigger tow truck, of course, and wish that they’d checked the ground for hazards first. This could go on for a while, I hope they all got home eventually.
