>So, a Catholic check out operator should be able to refuse to serve a customer who has a pack of condoms for religious reasons? or a Hindu can refuse to sell and scan beef and on it goes. People like this, they should move to a country that can accommodate them.
No, but they can ask their employer and the employer can make alternative arrangements if they think it is in their interests to do so. I would be wary as an employer about making concessions but employers are often pretty good about accommodating different requests/needs- eg childcare responsibilities, disabilities, being under age for sellling alcohol, etc.
