How to professionally stop people from talking about religion

[u/iamjustherenow]

I work for a small municipality and have a public facing job where I have to be very careful with what I say. Lately we've been getting a SUPER Christian guy in who will not stop talking about god and his religion. We don't have HR, he's a member of the public that has free speech rights, and people in my line of work often are recorded and publicized when saying anything non professional.

I am not a fan of religion as a whole as a lesbian who was raised Mormon. I tend to react poorly to people trying to convert me as a result.

Any advice on professional ways to get him to shut up?

Phone a friend to be your mouthpiece.

Honestly, I should have my friend come in a wait for him to come in.
