Letter: An interesting calculation

Sir: John Aitken, an analyst at the Union Bank of Switzerland, believes that 'customer whingeing is unjustified' ('Overdrawn on goodwill'; Weekend, 13 August).

My 'current plus' account with NatWest has an average balance of pounds 200 and for this loan to NatWest, the bank credits me with 0.25 per cent gross interest per annum. Recently, the account was overdrawn by pounds 21.03 for a period of four days, for which I have been charged the going rate of pounds 9 (nearly 4,000 per cent gross interest per annum).

Would Mr Aitken consider it whingeing to complain about such a disparity?
