I had an incident like that when I was working at a Honda Dealership as a service advisor. A young collegiate co-ed had came in to the service area complaining of a dragging or scraping noise coming from underneath the vehicle.
I went outside to her car and discovered a splash guard had partially torn off from underneath the front of the car and was probably the source of her noise that she had complained about.
I asked her if she would like me to remove it or at least cut the dangling part off for her so it didn't drag on the ground anymore. She said sure and I promptly produced my Cold Steel Gunsite folder and lopped off the hanging plastic.
Her jaw hit the floor when I had it out and open so quickly. After I cut the plastic off, she then smiled and said that a knife of that size was pretty handy huh.
I agreed and wished her a good day. Too funny.
