In some countries bitcoin cannot be use to buy Real stuffs like food clothes and other goods and services but even though bitcoin can be used in plenty of ways mostly in the cyberworld it is used in online markets like Game Credits, Gadgets some use it in the dark webs to purchase weeds,drugs. Others are trading it to a different crypto-currency or exchanging to dollars, so how to you use it ? 
Here in my country. Only few shops are only actually accepting bitcoin. And they are very far away. What i usually do is i convert it into cash so i can buy stuffs i want. I usually buy foods, clothes and other necessities. Bitcoin here in my country is not that popular. I think thats yhe reason why theyndont directly accept bitcoin as payment. Once all people here starts adapting bitcoin. Im sure many shops and establishment directly accept bitcoin.
