SELLS EXPIRED FOOD,GOODS AND PRODUCTS!

On the 02/03/16 just after 17:30,brought a few things at the garage pick n save convenience store.as I walked out and checked the expiry date on these things only to find they expired. then went back immediately and ask for a manager or owner. was referred to someone who am certain holds no high position in that store. when I asked him why they selling expired goods and this is not the first time I come across such, his response was \if we selling expired goods, what should I do?\"I just walked out, as I walk out his comment was \"they always complaining, don't come buy here again\".my concern is if my kids have eaten these things, then got sick, would they take responsibility for medical bills? cause clearly they don't care about their customers.
