The food industry in the world is so huge that if they start accepting payments in cryptos then it would make half of the mass adoption possible for the whole world. But, there are some ifs and buts like the countries that have made crypto payment illegal won't allow such things to happen. Moreover, some food shops have franchises all over the world which might be problematic for some.
Hey Little Pixies,
I think you make a good point about the country-to-country problems that will arise for large companies. Fortunately a lot of the food industry that is multinational is franchised so it would be easy to allow stores in the US to take crypto and stores elsewhere to not accept crypto.
