Where I live, you wouldn't get much business selling something for bitcoins at a lemonade stand or yard sale. Not that it's not a good idea overall, but there don't seem to be many people where I live that know about bitcoin.
I know, as people are not used to pay bitcoin in real life like in stalls or hawkers.It needs more technicalities,takes time to process or several minutes for confirmations. But,one day,I hope this will be solved,no waiting time for clearing.
