Disgusting expired steak. Disgrace

Bought a NY strip steak last night 04 March 2016. It was not past the printed expiry date. When I cut into packet it stunk up my house. The service at this outlet is normally atrocious however unfortunately this is to be expected at checkers these days, however this is unacceptable. You hide behind legal disclaimers and the like but what I can tell you is I will be shopping at the spar upstairs now. I advise all other customers to do likewise.
