What are scrooge's servants doing when he visits them with the ghost of christmas yet to come?

When Scrooge and the Christmas Ghost see the servants of Scrooge they're in a very seedy shop, selling off any of Scrooge's things they've been able to take from his home.

Scrooge got to see what's going to happen after he's gone. Next, Scrooge hears some friends talking about a man who has died.

They pay very little attention or consideration to the matter and Scrooge wonders who they mean.

As he accepts his possessions as being sold, he knows that people care less about his own death. Scrooge has certainly paid as little as possible for his servants, and now that he is gone, they are selling off whatever they can take from his house.
