No one was blocking anything. But the dumb cop had no patience and no brains.
It really is too much to ask people to think.
She was blocking the drive thru. Both the cop and the McDonald’s guy said that.
She was blocking the the path from the drivethru window to the street so that no other cars could exit the McDonald's parking lot.
Google's satellite map reveals that the area she was blocking was the exit point for both drivethru customers and regular customers exiting the McDonald's parking lot.
But the dumb cop had no patience and no brains.
He was quite patient - he gave her 20 whole minutes to move her car one foot.
That's approximately 1000 times longer than was required.
I'd say it was intelligent of him to wait long enough for her to prove what an unhinged jackass she was before he took her in.
