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.
using lightning sure its possible!
Agreed, using BTC for direct transactions would make no sense, but them creating the MCD token or perhaps using an internal blockchain like the exchanges might work. But, as long as crypto becomes more useable, I am all for it. I can say this though, I sure don't want to wait for my burger while confirmations occur!
