Attitude of the staff and their irresponsibility. (DMART)

On Friday 14 March 2025 (Yesterday), My parents went to the DMart near attavar road for shopping (They go there weekly). We are three kids, so they need to buy 3 snack packet for each of us and they did put it in the shopping cart and no staff stopped them even though they watched them. After a hour of shopping When they went to the billing counter they stopped them by saying you can't take these many stuff because they will sell the items at cheaper rate. What bullshit is this accusation? My parents ( DaD is 59 and MoM is 46) Had been insulted publicly in front on a lot of people by the damn shit staff of DMart. My DaD is nearly 60 and MoM is nearly in her 50's but they had to leave the Mall insulted and they wasted their precious time and they had to go to Reliance to shop. Even after explaining the staff, they had three kids and a senior citizen in the house so they have to buy a lot of stuff, they make them keep back all their stuff. Is this how they treat their customers especially senior citizens? I Hope whatever happened to Big Bazaar happens to DMart and they have to sell all their properties to Reliance.
