Builders Warehouse treating us as ********s

Over the past few months this business has grown from being a pleasant experience to being treated like a ******** upon exiting the premises with your package. Obviously they do not trust their cashiers and, rather than sorting them out, are now treating every customer as if he/she has ****** items in their possession that is not on their till slip. At this point every item's barcode is checked against the list on the till slip!! I have vowed NEVER to set foot inside or purchase anything from them again.
