This thread just keeps on giving.
I can't think of any better motivation than this for guys to work harder, be successful and earn more money so they can punt more attractive women. However... these gals aren't cheap: many are £100+/hr. In their areas, there must be more attractive SPs around at those sorts of prices so I can only assume that punters are choosing to bury their bones there. Probably to dig up in a year's time.
