Expired products

Good day everyone. I would just like to inform you about Pick n Pay liquor at Kyalami on main Shopping center. We bought a packet of simba chips that was expired. When taking it back we waited 30 minutes for the Employee named Neo to come strolling in to the shop for him to then swear at us and throw the packet of chips at us.. He then proceeds to go and take a furthermore 5 packets of expired chips off the shelf then tries to blame simba but not the people who packed the shelf. So how many other people have bought expired products from them.
