There are actually smaller establishments that accept Bitcoin as payment. I have heard that statbucks is accepting Bitcoin as well as Mcdonalds. I'm actually paying my tuition fee online through Bitcoin as a payment and it's more convenient for me.
Even if they are providing BTC as a payment option, not many are actually using it due to the fee problems and TX times. This will change in the future once LN becomes fully operational along with other positive developments.
But the positive dynamics shows that in the coming year the number of retailers ready to support this undertaking will grow to a giant scale, which makes me very happy
This won't just happen within a year. It will take several years down the line as more and more institutional investors continue investing in this market and as developments move along at a regular pace. Adoption will move upwards in a slow and steady manner.
