Just asked a local coffee shop about accepting bch, and I need some help with the follow up conversation.

I just asked the general manager of a local coffee shop if he had ever considered accepting bitcoin or other crypto currencies and he had no idea what I was talking about. I've read a few things on here about getting vendors on board and I feel confident that I can at least explain the basics to him, things like setting up a wallet, sending and receiving, etc. However I DON'T feel comfortable talking about it in terms of his business, such as taxes, fees, exchange rates, these sorts of things.

Where can I get information that will answer his questions about how to handle crypto currencies for his business. I want to be knowledgeable enough to show him that he can get new business from accepting crypto and make him feel comfortable accepting it.

Currently I would center the conversation around BCH as it's the one I'm most comfortable with. But are there any other forms of crypto that are important or useful to a small business like his?

Anyone had success introducing crypto to a small business and have any advice just in general?
