Liz here,

I work for Tesco and they dont attract the chav element that is why they are the number one supermarket in the country going from 5th to 1st in my humble opinion that in british business is a fantastic achievement, Tesco customers come from all demographic categories and appiele to all shoppers. This sounds like a one off incident and there is nothing Tesco can do to stop someone having uncontrolable children. Sorry for the rant but have a think at the question its the parent not the supermarket.
