The older guy is arguing a point with the younger guy, who is reading from a newspaper. If that's all there was to the picture it would be OK, but look how he carries the story further.
1. Reaction figure.
The third guy at the table is bored out of his mind because he's heard these guys arguing the same point endlessly. However you read his expression, it suggests layers of backstory.
2. Internal crop.
The guy wearing the ornate blue jacket at the far right is cropped by the column, so we only see a little of him. No need to show more than that.
3. Shadowed elements.
The guy he's talking to is keyed way down in shadow so as not to compete with the main action. But we can see he's gesturing and probably talking politics, too.
4. Repoussoir figure.
The figure on the far left is facing back and to the left. He's cropped by the picture's edge, suggesting another conversation offscreen. Even though he's a throwaway element, he's painted carefully.
At the top of the picture is a mirror, and the reflection (see below) shows a scene at another table.
If you're working on a storytelling picture, look for ways to include reactions, internal crops, shadowed elements, repoussoir figures, and reflections.
