A very weak case. She is being asked to serve it, not consume it. The person to whom she serves it may or may not drink it, as they see fit. The purchase or the dispense of alcohol has no connection to her religious beliefs because she is not the seller. Her employer is the seller, therefore she is not “taking the price” from the customer.
So it has been written.
Heh heh heh ...
If she wants to take the strict approach and refuse to dispense alcohol even though she does not drink it, then that is OK. But she is also dressed in a attendant’s uniform in which either the shape of her posterior can be determined (pants suit) or in a dress that exposes her legs, both of which may be sexually provocative to males. Based on that, she is dressed as a slut and should be raped. And then she should be stoned to death for the crime of adultery. All part of her beliefs, you know!
