I would like this happen as well to my country specially those renowned food establishment. I just don't want to use my bank's ATM card directly and I want my bitcoin wallet to be in use when ordering my desired food online because I'm separating the funds on my bitcoin and on my atm which is what I used at work when getting salary.
LOL.. if you are directly paying from your Bitcoin wallet, and in case the confirmation takes a long time (30-40 minutes), then what are you going to do? Are you going to wait until it gets confirmed? A better option would be to use a third party payment processor such as BitPay or PayPal to make Bitcoin payments. PayPal hasn't enabled cryptocurrency payments yet, but I heard that they are planning to do it by mid-2021.
