Car parks are to smell of roses and freshly baked bread in a bid to bring back customers turned away by the usual aroma of vomit and urine.
Car park company NCP ran a survey and found that bad smells were driving away up to a third of its custom.
Using new technology, it now plans to pump smells such as flowers and freshly cut grass into stairwells.
Those surveyed said they even thought coffee, bubblegum and petrol were pleasant aromas.
NCP chief executive Andrew Potter said, "We are committed to offering our customers a pleasant and positive experience in our car parks, and we fully recognise that unpleasant smells could drive customers away.”
Of the 2000 people questioned, around 60 per cent said that the stairwells were the worst part of a car park.
