I've paid for app unclock using bitcoin cash and I've also bought VPN service with LTC before, crypto payment options are now getting popular right beside MasterCard payment options, I've not seen or pay with my wallet offline before like in the real world only online.
Right, I forgot that I paid for a VPN as well. Also for some IP tv service I've used for a while. Bit, like you, haven't paid for anything in the "real" world.
