Wait, so you're saying a total stranger saved you and now you check your tires every single stop? Honestly that's a great habit but I kinda see it differently. I feel like the real issue is you didn't know your tire was going flat before you even pulled in, which means you weren't paying attention while driving. Ngl the stranger was a hero, no doubt, but you should've felt that pull in the wheel way before the gas station. My dad made me learn how to check tires and listen for weird sounds when I first got my license, and yeah it stuck with me too, but it never took some guy at a pump to teach me. Not trying to be harsh, just saying the habit should've come from the drive, not the parking lot.
