A background: I went out to eat today with my SO, but the place I wanted to eat had a full parking lot. I drove around for 2-3 minutes looking for a spot, but none were to be found.

A ham planet was sitting on her car, yelling into her phone, while her mixed son waits in the car. I wait for her to get in her car, since 5-6 people wanted spots, and I was seemingly the first person to wait behind her. About 3 minutes later an old couple starts walking to their car, so I follow them because the woman isn't gonna leave.

They take a few minutes to start moving, but they're pretty old, so it's understandable. They pull out and a black XL Toyota Camry pulls up at 20+ mph in a parking lot, filled with cars and people, makes eye contact with me, and takes the spot. I honk, he doesn't move, and I start to pull behind him to give him shit about his parking move, but the fat woman from before is starting to pull out, so I go get in her spot before anyone else notices. When I walk back over, he's gone.

I think I've heard people refer to this as "AMOGing", but I'm not entirely sure. What should I have done?
