This was my experience with it going on a decade ago. Then my buddy and I both got Coinbase accounts and had fun being able to instantly pay each other with bitcoin (off-chain) - hey here's that money I owe you for lunch... in bitcoin. Of course, since it's off-chain it sort of defeats the purpose of bitcoin, right?
