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.
I think it can make sense but as you say whether the price paid is appropriate for the price of the food that the buyer is. while bitcoin prices are unstable. I personally still need enlightenment to use bitcoin to pay for food. But whatever the outcome if positive we should support the trip because it is a revolution and progress for bitcoin in this country.
