Good to see you can use bitcoin to buy your daily needs, which means bitcoins is readily available in your local shops where you can buy with bitcoins. In my country there are not much options available in local shops so i mostly use bitcoin spending online or in most cases i have to convert my bitcoins in fiat and then use them for fulfilling my daily needs.
Why don't you use bitcoin debit card dude? If you have bitcoin debit card you can easily save your conversion fees from bitcoin to fiat currency and using bitcoin debit card doesn't involves any fees so it can save your lot of money and at the same time you can use it at any place for shopping either online or offline.
It can be good to use a BTC debit card, but I think there aren't all countries who accept this kind of card on machines because of "flag". I already saw someone using it in Canada, probably in the USA it's allowed also.
It would be the most simple way to convert BTC to fiat instantly, but are you sure there isn't any fee? Because the middle man service must charge something, no?
