The 'fun' (ugly?) face of the City

The one thing that surprises me - given the amount of ever-more sophisticated technology that is available - is the survival of the voice-based interdealer brokers. As this incident demonstrates the level of sophistication needed to fulfill the role of go-between is not all that great. So may the level of 'client entertainment' have a significant role to play? Sooner or later the penny will drop and another source of generous income for many staffers will be rationalised away, or fall foul of tightening regulation.
