Real Canadian Superstore Prince Of Wales Drive

I often shop at the superstore at east side of Regina. In general, people are nice. However, I shopped today and decided to return two bags of cherry, one of grapes and 2 bags of frozent shrimp as they dont look good but price is too high after 10 mins after purchasing. One lady at customer service counter was very rude. She told me that I cannot return as the food would go garbage. I used to return some produce product before without any problem. I read the return policy on wall but no mention.
