FRANK HANSON, of York, is keen to raise the tone of this column. 'You've had the 'worst airport' stories so why not a competition for the most expensive place for a pee? For a kick- off I'd like to nominate Helsinki Railway Station where the cost (in July of this year) was shown on a makeshift piece of card as 6 Mks (about 75p). Previous prices of 4 and 5 Mks - although pencilled through - were still clearly visible.

'Two weeks later the price had reverted to 5 Mks, which suggests that there had been some price resistance and that the good citizens of Helsinki had been relieving themselves less expensively elsewhere.'

Can anybody top 75p for a visit to a convenience?
