Does that even make sense with the current transaction times and fees? You are going to pay more for the fees than for your meal. Unless the fees go down drastically, it makes no sense to use bitcoin as a daily payment method.
It makes sense since we are now in a modernized world where every transaction is in online therefore it is a great beginning for us to adapt this kind of ways in buying online. Our goal is to make bitcoin acceptable in our country then it is a big step to make it possible.
This will be very great if bitcoin will used as currency to buy food and for those who are holding their coins or have coins in their wallets will enjoy a serious benefit of bitcoin and I think this should start soon and McDonalds is taking a great step and they will be pioneer in their field in adopting bitcoin and this is convention that pioneers get blessed more than others and by seeing footsteps of other franchises will come in.
