Woolworths review: deli service of frozen fish

I went to this store today and wanted to purchase 1 kg of frozen south african cod filllets as I like to keep them in the freezer so they are available when I want to use them but was informed that they weren't allowed to sell them frozen as the price was different from frozen to fresh. Are Woolworths so narrow minded and cost conscious that there is a big difference between the price and weight of fresh and frozen fish Does this mean that at Christmas that I cannot buy either 1 kg or 5 kg frozen prawns but must buy them defrosted for (your convenience) not mine I am not complaining about the service at the deli counter only about the rules which have b een placed on the staff there. Should I now change my shopping to Coles or IGA instead of Woolworths? Only you have the ansers to this question
