Since the subject is a large business like McDonalds I did a brief research on the content but unfortunately I couldn't find any definitive information about the reality of the incident. Since Bitcoin and other cryptocurrencies aren't yet accepted as a legal payment method by many governments I honestly don't think that such a large business will accept payment with Bitcoin or other cryptocurrencies. For this reason I don't think that the information and images in the content can be correct. Additionally, I have some doubts that this post is not up-to-date because the full menu content is not visible and the amount paid corresponds to around 45 USD with today's prices.
Finally, I think that if a large business like McDonalds starts accepting payments with Bitcoin or other cryptocurrencies this information will be announced quite quickly through reliable sources. For this reason, I think this content isn't accurate as there are many questionable details about the current situation and it has not been verified by any reliable source.
What you say seems to make more sense. Because the information provided is not enough to confirm that it is the truth. It's just that when talking about McDonald's accepting bitcoin as payment, I heard about it last year
1. But I haven't heard it again this year. So I don't know whether they still accept bitcoin or not. And McDonald's only accepts Bitcoin in a few countries. But for the transactions that occurred in the OP, I don't believe it yet. But I still believe that it could be true and happen at McDonald's which accepts bitcoin in certain regions or countries.
