The problem is not all people know about bitcoins, even in my area only 4-5 people know about bitcoin. Before we encourage local businesses to use bitcoin, we need to introduce them first about what and how is bitcoin works. I'm sure they will start using bitcoin if the buyer want using bitcoin as the payment.
At present same is the scenario around most of the parts of the world. Very few were aware about bitcoin and based on the fact it is really hard to make a bigger profit through offline services. What I suggest is, while planning for bitcoin acceptance it needs to be prioritized for long term profit making.
