An unemployed dude comes to your house to ask for off jobs, say to throw away your thrash and mow the lawn. You had no cash but he owns a bitcoin wallet and asks to be paid in bitcoins. Would you pay in bitcoin?
I don't really see anything wrong with that, as long as I have the money/Bitcoin in my wallet, I would pay him with it. Unless I'm saving the money in my Bitcoin for something else, but still that wouldn't be a problem because I can easily fund my Bitcoin wallet by using my bank debit card and it's really fast.
So, if anyone should ask me to make payment to them with Bitcoin, I would for sure, also depending on how they ask. I have only done that once, sent payment to someone through Bitcoin after he completed a little offline task for me. He first asked if I make use of bitcoin and whether I can pay with that and I replied yes and asked for his address.
