Had a guy this morning that made 3 separate orders for the same thing. All got cancelled because he didn't pay the lightning invoice. So I reached out to him to find out if there was a problem with the invoice showing up correctly. I checked my node, and everything appeared to be running correctly.
He replied, " I'm not spending Bitcoin. I want to give you dollars."
