Food I returned was just put back on shelve!

I bought a bottle of Anchovy fillets at Woolworths yesterday. When I unpacked it, I saw on the lid: \Safety button pops up when original seal is broken". I then realise that the seal was broken.<br> <br> This morning I took it back. The guy that helped me did not even look at my proof of purchase. He just went to the shelve and got another bottle. What was most disturbing was that he just put the bottle with the broken seal back on the shelve (fridge).<br> <br> How can Woolworths do this. You cannot put food back to resell it"
