(Rant) Wife denied from getting food at Taco Bell.

Today my wife went to Aeon Cheras Selatan and wanted to get a take away lunch at Taco Bell for her and our daughter. She's Malay Muslim but she cannot fast today due to her period. When it was her turn to order the food at the counter, the staff apologized and told her that they cannot sell the food to Muslim before certain period.

My wife said she only wanted to take away the food but the staff still insist that they cannot sell the food because of the new policy enforced. My wife was embarrased and upset by this and leave the restaurant.

My question is, are this thing common and legal? Should my wife lodge a complaint to the management? We never experienced this issue before.
