Like what feeling exactly? Isn't it the same feeling after making a transfer from your bank app for a service rendered to you? I haven't paid for a food with Bitcoin but I don't think doing so would give some kind of inexplicable feeling since I'm even spending from my coin.
Indeed, I am also very curious about how people who pay with bitcoin feel. What kind of feeling does it give them, to the point that they can't even put it into words? While we all know that bitcoin is also money and is like payments method with bank account, USDT or card. I'm a bit confused to see OP describe paying bills with Bitcoin as if he won the lottery.

Although, it's a nice idea from your friend to consider accepting Bitcoin as a payment method but it doesn't make sense when it's a meager amount considering the cost of transaction and confirmation process.
That's not a good idea because it's not new, and we've been discussing it for over 16 years.
