OK guys... so I had a chat with one of my Italian Facebook friends, and he confirmed that Cooperativa RadioTaxi 3570 is not accepting direct payments in Bitcoin. They are using a third party payment gateway. Users can pay with Bitcoin, and the driver will receive this payment in fiat. The drivers doesn't even know that the original payment was in Bitcoin.
So, the story is a bit different but actualy this doesn't have to bother the Bitcoin users, it's doesn't make the difference for them. They can spend the Bitcoin and drivers are getting fiat money so everyone is happy. At least I think so. And no matter the indirect payment it's still good promotion for Bitcoin.
