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 am also thinking of these when I read the 'news'? It is not possible to use BTC for this little amount of p unless the transaction time can make with in a sec. and the fee is as low as some cents. Otherwise BCH or IOTA seems much more suitable for daily basis.
