Expired goods

I went to buy a combo special of R 38 at the King Pie at Lakeside Mall today. The combo consisted of a fish burger pie, chips and a can of coke light. Firstly the pie was soggy and was heated in the microwave. Secondly the chips I received was not even half of the portion packet and it's advertised as a regular chips if I'm not mistaken. And when I was driving off to think about how expensive the special was I opened the can of coke light, had a couple of sips and it tasted funny. I checked the expiry date and it expired 18 June 2015, that was it. I didn't even bother to return to the outlet because I doubt anyone there will do something about it because just to mention. The staff open the greaseproof paper packets with there hands!!!!
