I drive rentals pretty often. One of the last was the "Queer as a football bat" Cube. I'm backing out of a parking place when I see the wind has blown a cart and it's heading for someones car. I throw it in park, jump out, and catch the cart.

Then realize the POS car had some kind of auto lock thing and has locked me out. $70 later and my good Samaritan self is back in the rental driving home.

No good deed......
