Rudeness in Greenstone

I go to food *****s all the time and have never had issues with anyone. Most of the managers and staff know me because i always travel with my children when grocery shopping. But yesterday the 12/12 I received the worst ever service at Food *****s market in Greenstone. I had queried a price variance between what was displayed and the amount that was punched in. I queried with one of the managers the one manager was polite but the other one was completely rude and when i walked away he told his staff "don't worry about her she is a chance taker" this is when i lost it and reported this to the other manager. I have never experienced such rudeness in my life.
