Driver forgot to engage the parking brake causing the vehicle to pull off the parking spot blocking the way

I saw a post earlier today showing a vehicle pulled out of the parking box in a parking garage. When I was going back from work today there was a black VW pulled frpm the box at the parking lot.

After I took the picture, I pushed the car back to the spot by rolling its wheels and secured the drivers side front wheel with a piece of birck. I then left a note at his windshield wiper tl check the brick before moving out.

I might have saved the guy a couple of € for parking ticket or towing as this spot is frequently patroled by the town police.
