Cub Foods

My family has gone to the cub foods in Eden prairie, Mn for years. My mom has used a check to pay for her purchase. Her check has a Minneapolis address well today the Manager asked for another method of payment because they only allow local checks. Mind you nowhere in the store is that posted and we have gone to that same store numerous times using a check never had any issues before. The check was good it went thru but she saud oh since this is a Minneapolis check we need a differnt form of payment. We asked when that became a polocy or a rule of that cub and she says its been for 24 years since she first started. Hmmmm weird because we jave gone there before and never had the cashier call a manager over and we have NEVER been told that that Eden Prairie Mn cub only takes local checks. She said they have had alot of people go there with bad checks from Minneapolis but again thats not us. We have never had a bad check they have always went thru. Also the Manager was very rude. I dont understand how they jave had a polocy of only local checks for 24 years when at least 25 times in the last 2 years a check was used thst always went thru we have never been told that. To me this is discrimination. You mean to tell me only Eden prairie addresses on checks are accepted at that cub? I think not.
