How does Scrooge's and the charity collector's relationship change?

Answer 1

In stave one Scrooge rebukes the charity collectors throughout their plea for a charitable donation, citing the use of prisons or workhouses and even the dreaded treadmill as an alternative to being poor.

In stave 5, Scrooge has made an oath that he will keep Christmas in his heart throughout the year, and on finding the portly gentlemen in the city of London on Christmas Day, he whispers an untold amount of money in the ear of one adding that it includes interest for all the years that he failed to help. They are both shocked at this and of course delighted.
