The London recessionary shirt shop advert reminded of the old FT model using a Mars bars as a measure of inflation. Indexation by Mars bar instead of currency. Wednesday's base rate change may have ironed out the effect on shirt sales, but I'm not sure it will sweeten confectionery sales. Something to chew on, anyway.
How much IS a Mars nowadays? Roast beef at Simpsons is £19.95 with all the trimmings.
