When you pull your car up to a store here, a little man comes up and nods at you and you nod back at him.
This is a little contract meaning he will look after your car while you are in the shops. When you come out and you're ready to leave, he comes up and you pay him. You can really pay whatever you want, usually just some change.
One time we were leaving and I didn't know about this arrangement and I got in the car and a man ran up to my door. Mineska sped off, and I freaked out. Well she figured she didn't have to pay this one because the nod didn't happen. He only showed up when we left and so she had no idea if he really watched the car. So she didn't pay.
