Bad Rice and Beef Stew

I work in Rosebank and PicknPay is the cheapest place to buy lunch during lunch hour. Yesterday I bought there cooked rice and cooked beef stew for lunch, I shared with my colleagues when I got back to the office, all of us who are the food did not sleep last night because of running stomachs and vomiting. Please can we be served fresh food that has not reached the expiry date otherwise one if these days it will not just end with diarrhoea and vomiting.
