A clash of civilisations took place in Manchester last week, with the Building Societies’ Association parking its annual conference next door to the Mortgage Expo.Although the gatherings were within spitting distance, the short skip between events transported you across different worlds. Delegates entering the BSA were treated to a distinguished gentleman playing grand piano, a shoe-shine stand and somewhere to practise your putting. Meanwhile, the garish world of Mortgage Expo was an explosion of champagne in plastic flutes, women dressed as brides, women dressed in very littleâ¦ in fact, women dressed in whatever a mortgage broker could desire. But no pole dancers this year. Perhaps the divide is closing.
