To pass the time I resolved to discover the differences between the two groups and- if this is possible- to teach 'richness' to the poor.
This behaviour seems to be a form of religion among rich people. They respect small sums of money out of a kind of respect for money in general. They will buy quality when it pays to do so- but they will never just throw money away no matter how small the sum.
These photographs were taken in a City pub where it is possible to drink real ale and be instructed in the virtues of thrift by monks as we do so.
