Lights, Camera, Action.

(From 1:12 to 3:38) - Not the whole ten minutes, only 2 minutes and 26 seconds.

The scene starts with the camera performing a dolly shot, tracking a man who is walking in a garage.
The narrator (who is also the man walking) contradicts himself while talking about black people when he says, "If I got one thing against the black chappys, it's this, no one gives it to you, you have to take it". The lighting has been set up so that he looks like a 'black chappy' himself - There is no light in the garage, but there is daylight behind him, creating a silhouette of the man.

When the scene cuts, the camera is placed into a first person view, and immitates the man walking into a diner. Notice the "DON'T WALK" sign to the left, yet the man is still walking across the road - shows authority. Without any scene transitions, the camera moves out of first person then pans to the left, revealing the manCostello standing at the counter, but only showing his back.
There is a close up on both man's hands when the exchange of money takes place, this is to show detail of what's just happened.
"It won't happen again Mr. C" anchors the importance of the character; the auidience now have a name of the man walking at the beginning, and they would probably guess that he is a gangster.

The soundtrack to this scene is Gimme Shelter - The Rolling Stones, this adds a certain amount of 'coolness' to the whole scene, and gives Mr. C (formally Costello) immediate authority over everyone.
The music changes to a more, easy listening song when Costello makes the owners of the diner give the young boy at the bar a couple of loafs of bread, a couple of half gallons of milk, mayonaise, baloney and cheese and comic books. This is exceedingly generous, it shows his authority over the owners of the diner.
It then changes back to The Rolling Stones when he is walking across the road, with an over-the-shoulder shot of Costello looking at him.
