Hidden expiry date

I bought a Juice from the Spar yesterday morning when i noticed that it tasted bitter i checked the expiry date only to see that the original expiry date was covered up by a sticker and a new one had been placed on the lid<br> <br> The original expiry date had already been reached and they were clearly trying to get rid of stock by disguising the original dates. <br> <br> When i returned the juice, the attitude i received from the staff was disgusting!<br> <br> I will NOT be going back there again.
