In today's situation many people do not know about using bitcoin. We buy things from small shops and platforms the shop keeper does not know about bitcoin. Therefore it is very difficult to use bitcoin in our daily use. But the day will come, every one use bitcoin for buying and selling.
I think that can be solved by asking the shopkeeper if Bitcoin is accepted, and if he asks what Bitcoin is then explain it. That takes a lot of time but can have results over time. The more people there'll be asking for Bitcoin, the more people will accept it as a payment and use it.
