The next time an unlucky politician is criticized for not knowing the price of some common grocery, remember this:
More than one in ten respondents could not give any price for a carton of milk or a packet of sausages in euros, while those few who did logged an average error of almost 30 per cent.
And yes, things used to be better in the old days:
In a similar poll taken before euro notes and coins hit the tills in Finland found that nearly all respondents could provide some sort of estimates of the prices of staples, with errors remaining below the 20-per cent mark.
For the record, I missed the price of milk by 11 cents.
