Expired juice

<p>Here I was thinking pick n pay sells good food. Trusting as I was I don't check any expiry dates on their food coz I trust them.</p> <p> </p> <p>On Saturday I bought my groceries and in there I bought my house holds favourite juice (red g****. Pick n pay brand 1 liter)</p> <p> </p> <p>When my daughter drank it she noticed some funny taste but as she's only 9 she didn't say much. </p> <p> </p> <p>When my husband n i had a sip we could taste its old n rotten</p> <p> </p> <p>What I can not get. Why sell something that expired a month ago</p>
