Checkers brookside employees self test product for the customers

Last night 31/3/2024 shopped at checkers brookside with my mum she asked me to purchase bio plus sachets for herself I picked up a box and it light so I decided to open the product only to be shocked in a 12 pack box their was only between 4 to 6 packs had I not checked I would have purchased it thinking it was a full pack then reported to assistant manager but was told the manager will call me about it. People please becareful brookside employees self test the products before customers purchase it. It is a so called secured area as per assistant manager cameras guards I’m shocked.
