When customers shove their religious beliefs down my throat at work

Twice, I have been given this now by two customers.

Now, I'm open to other people's beliefs. I'm not religious, I do believe there is a higher power but I don't know what that necessarily is. I have no problem with people talking about their religion, I actually find it interesting.

However, what I don't like is when I get pushy *ssholes like these guys preaching to me. When you give me something or say something like what is written on this note, it makes me want to shove it back in your face.

I will live my life the way I want to. So DO NOT tell me I should do everything that a book says is right. Thank you very much.

What are others opinions on this? What would you do if a customer gave you this?
