Accepting bitcoin for food services does not seem realistic to me. The reason is obvious. How can you expect your transaction to get confirmed after you ordered?
Yeah like when you ordered you need to wait for the transaction to be confirmed and that's the only time you can get your order? Like what the heck is that?! You starve to death before you can eat. That's why I prefer to pay cash than btc to fast food chain or restaurants.
Uh, usually if you pay with a big enough fee it would make sense that they accept it with 0 confirmations because the risk of someone being caught CCTV and being jailed is just too much for a scammer. Plus, there are way more double spendingc opportunities online when they can stay private and for bigger amount than just a big burger...
The main issue isn't confirmation times, but rather transaction fees. It seems like Burger King is going to accept bitcoin probably through Bitpay, which means that you're not only going tohave to pay 0.0007ish bitcoins in miners fees on your end, there is also like 0.0007 btc in deposit fees for bitpay. So you're essentially paying $4 to just pay with bitcoin. It would make sense if you only had bitcoin on you, but wouldn't really make any sense if you had debit card funds.
