Cub Foods review: Service

Had an issue with one of the self check out machine and asked for a help. A staff named Katie was very rude and unhelpful, instead of helping us with it, she made me stand there for 10 minutes and she started arguing with us. She should not be facing even a customer, never have I ever experienced something like this before with cub food. Please make sure that you guys do something about it, I m pretty sure I am not the first customer to be complaining about her, and if you guys are receiving complaints on her, you guys need to take action about her.
