[US] Man Asked Me To Help Charge His Car. Seemed off.

I was charging my car (at a Tesla supercharger) when a man knocks on my window. His car is in front of a charging spot, and he asks if I could reverse his car into a charging spot for him. He said he couldn’t do it himself. Entire thing seemed off so I said no, and he just drove away. There were multiple open spots so anyone could reverse themselves without hitting another car next to them. And he didn’t seem to even ask anyone else for ‘help’, just drove away after asking me.

I’ve been trying to figure out, what was the scam there? Has anyone seen this before?
