SPAR Miramar food

I went to SPAR today to buy something to eat at around 14h00. I got myself 6 chicken strips and a chicken and mayo sub. The chicken strips had a chemical taste to them and so I thought that, maybe it's just the 1 but all of them had a chemical taste to them... so much so, that my tongue is numb. The chicken and mayo sub was equally impressive... the bun was super hard and I was afraid to even try it as in my mind.... if the bun is this old, how old is the chicken? I went back to the spar and walked directly to the manager's office, told them what I experienced and gave them their food back. I didn't insist on my money back and there is NO way I will eat something else from THAT SPAR again. I think this is so disgusting that a SPAR would sell their old expired buns to the consumer and run the risk of a customer getting food poison from their chicken strips. I made a audio recording where I walked in and gave them their food back, just for incase someone wants to turn things around on me. I won't buy there again!
