Bank problems

The RBS Bank group has been badly hit by a computer glitch that stopped people accessing their own money. Not surprisingly there is much anger, frustration and downright embarrassment amongst their customers on a day of high consumer expectation as the Christmas rush gathers pace.
Customers eh! Aren't the public a pain with their wants and expectations? Wouldn't banking be a great business without them? I'm sure there must be many in the Banking industry, happy to make their money on the trading floors, that must think like this.
