It may be considered an “international company” but the operations more particularly their franchise are obtained locally by another local domestic corporation. That's why you will only see Burger King in Germany that accepts Bitcoin and no other countries have it, it's more of a local decision by the partnered domestic company rather than an international move unlike Steam in which their decision to accept BTC affects all customers across the world because it is only ran on one client. So if you are seeing fastfood related companies accept cryptos don't expect all branches will be accepting crpyptos as well.
