As they found out in Britain, accommodating halal in school cafeteria required the hiring of Muslim staff, but that meant not hiring non-Muslims.  But then, food had be from halal suppliers. That was good business for Muslim halal food suppliers.  Regular food suppliers lost money when schools stopped buying from them. Delivery trucks had to be halal certified, so drivers also had to be Muslim. It was done without public knowledge, and only realized when popular bacon sandwiches were no longer available. Cafeteria managers making the changes were Muslim, and refused to allow pork into school cafeteria, even trying to police what food was brought from home. They required halal certified fridges, stoves, plates, trays, cutlery and so on, to ensure nothing had ever touched pork.  It was blatant favouritism for Muslim run companies. It caused a real battle in schools. The same happened in retirement homes, hospitals, and prisons as halal took over.
