Why didn’t the ‘polished traffic’ stop at the roadside stand?

The ‘polished traffic’ refers to the insensitive attitude and gentlemanly appearances of the city-men. These people who passed by the roadside stand were self-centered and their minds were restless with greed for money and ambitions for great profits in their business.

The news in the poem 'A Roadside Stand' that is making its rounds in the village is that the villagers will be provided with homes near theatres and shopping complexes; that they will be taken care of; and that they have to worry no more.
