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.
