I have often wondered why some shoppers use their own bags to put their shopping in rather than the supermarkets own trolleys now I understand why, next time you are out shopping check the bottom of the plastic trolleys, they are filthy, really dirty.
I have also seen children sitting in the main body of the large trolleys leaving germs from the soles of their shoes and backsides in the trolley for the next shopper.
