I think if there were a lot of people that simply ask "do you accept bitcoin" this would make the business think to themselves everyone is asking about this bitcoin thing let me find out what it is and then once they look into it they may adopt it or even come back to you to ask for more information.
Other larger companies with an online space would have systems where they log support queries so over time if they keep getting the same query they will no doubt look into it or already be looking into it.
It seems to me that it is very difficult for local businessmen to get bitcoin. At once it will be necessary for many people to explain what bitcoin is. And then already try to implement this method of payment
