that's big-ish news if correct
So out of curiosity, I jumped over to a German server on my VPN and had a poke around the German Burger King site.
There is absolutely no mention anywhere on burgerking.de of bitcoin. Their FAQ contains the following quote under the question "What methods of payment can be used":
Je nach Restaurant haben die Gäste die Möglichkeit, entweder bar oder bargeldlos mit EC-Karte zu bezahlen.
Translation: Depending on the restaurant, customers can either pay with cash or with an EC Card. (Which is a type of German debit card).
Now, if you click on the "Lieferservice" link, you are redirected to
https://www.bklieferservice.de/. Lieferservice is the trading name of takeaway.com in Germany, as I discussed in my post above. On this page, you do indeed see the bitcoin logo. On the takeaway.com/lieferservice/lieferando website, you can find the following quote:
Wähle bei 'Bestelldaten' die Option 'Bitcoin' aus. Im Anschluss klickst Du auf 'Bestellung aufgeben'. Du wirst zu Bitpay, unserem Bitcoin-Zahlungsanbieter weitergeleitet.
Translation: Under "Order details" select the option "Bitcoin". Then click on "Place order". You will be redirected to Bitpay, our Bitcoin payment processor.
So, as far as I can tell, my post above is accurate: Burger King are not accepting bitcoin, but the service they use to provide home deliveries does (via Bitpay). It may be that Lieferservice have recently added the bitcoin logo to their landing page (hence the news story), but in reality they have accepted bitcoin for over 5 years already.
