A guy in a glow-green sweatshirt drove up in a huge pick up truck with a Bouncy House company logo on the door.

He honked.

His passenger got out and shouted up towards a top floor window while dancing around the parking lot with his hands held out.

A bearded scruffy guy with oily black hair poked his head out of the top tenement window.

He shouted, and tossed something small to the dancer. 

The dancer picked it up off the ground and ran over and handed it to the truck driver seated at the wheel. 

Then the dancer went upstairs for a few minutes and came back and they drove off.
