Did I Just See That?

As I was driving home I tried to turn into the store. There was a car coming up fast behind me and a car coming towards me. I was trying to gauge it so that I could pull across the road into the store's lot after the car past. Suddenly the car that I was waiting for pulled into the lot in front of me. I tried to pull in behind him but he just stopped. He was barely off the road and I was stopped in the oncoming traffic lane, my headlights aimed right at his driver's door. He looked up at me and I waved my hand to indicate that I would like him to move forward so I could get off the road. He started gesturing very angrily and rudely and pulled faces at me. I couldn't believe a middle-aged man was acting like a 2 year old. I couldn't help it. I started to laugh. I think that just set him off more cause he pulled faces at me the whole time he walked inside. I didn't think it a wise move to follow him as I seemed to rub him the wrong way, so I turned around and just went home. I'll stop by the store later.
