Expired Food

On 2 February 2016 evening. I drove all the way from Sebokeng for a full tank fill-up at Total Palm Springs. Once there I decided to buy my 5 year old son some snacks for his school lunch box. When I got home I realised there was a white powdery substance at the bottom of the Tropika juice I bought. I checked the Best Before date and it was expired. I fail to understand how the service station shop still has expired food for sale. My son is very allergic, I would have been an irresponsible mother if I had fed him the juice without first checking the expiry date. I am very disappointed because I was not expecting this at all. It is unacceptable, unsafe and unhealthy to sell expired food/beverage to unsuspecting customers.
