Last week I went to get my first covid vaccine shot, and I parked across from this guy. I got out of the car and he just started chatting away to me, he was telling me stuff like "keep your head up man, things will get better", and he kept asking me about what I was doing. His vibe was extremely methy. My girlfriend texted me while I was in there that he and the guy he was with kept talking to her and wouldn't leave her alone, and were counting piles of money and probably smoking meth in the front seat, she wasn't sure. When I got back out, the guy called to me and asked me if I could keep an eye on his car while they went in, and not let anyone go inside the car. I was like, alright man, and then he went inside. I was supposed to wait for 15 minutes in case I had an allergic reaction. Then, the guy came back out and I waved to him and started to drive off. Then he ran over waving his arms and shouting, so I rolled down the window and he was all wild eyed and asked if I saw anyone approach his car. I said no man, no one has been near your car. He looked down and then started screaming "FUCK!!!! FUCK!!!!" at the top of his lungs. I got out of there as quick as possible because it seemed like whatever was going on, it was one little step away from him blaming me for it. But then this old lady pulled out right in front of me and then took like 5 minutes to turn out onto the main road (busy street and she waited for there to be no cars within like an entire minute's drive from there), so I just sat there behind her, watching the guy in my rear view, tearing apart his car and screaming and looking increasingly violent. It totally sketched me out.
