Reminds me when a PCSO (UK police community support officer) knocked on my window and told me off for driving while on my phone. I was literally just scratching my ear. Also, I had managed to forget my phone at home when having to visit a clients office and didn't have time to go back and get it - I was in the car grabbing a quick lunch. I was already annoyed with myself anyway so was livid after that. Told them you shouldn't go around accusing people of things unless you can actually see it. They just doubled down and walked off without apologising or anything.
