Re: My automotive repair shop is accepting bitcoin payments
I haven't heard of anyone else in the automotive industry accepting bitcoin yet. In this area, I don't really expect to get anyone wanting to pay in bitcoin yet, but I figured I could do my part to help spread awareness.
You might be right - but offering a discount is always a nice incentive for people to get to know more about Bitcoin 
Just make sure offering a discount on a specific payment method does not go against the rules of your other payment methods (for example, if you take CCs, your bank might forbid that - I've seen contracts with that...).
