Decay fish bakes

I went and bought fish bakes this morning, and when I opened them at home they were decay, I then went went back and complained, I got a very nice manager who refunded me... But can they please check their products before selling to their customers, this is not fair as I had to take a taxi back to return the fish bakes.. They must think of us... I spent money returning the product, and wasted a lot of time going back... This is really not fair
