I was helping a lady at work change a flat last week and another dude who came in as I was finishing up tried to butt in and argue with me that I was putting the lug nuts on backwards. Even after I explained how they worked. I had to walk him down the lot and show him the rest of her tires and 3 other cars with them to get him to shut the fuck up about it. It’s extra stupid because he knows I used to be a mechanic. I’ve put 1000s of tires on. I know what I’m doing.
