Now there are very good conditions to accept bitcoins as a payment on your business. There are many great payment processors. But business just don't see reasons why they need to accept bitcoins. Bitcoin community is still very very small and it's very low possibility that business customer is bitcoin user and he may want to pay with bitcoins.
But adding it as payment option will not harm them. It's not with the number of bitcoin users but it's just a simple additional payment option including the regular ones since on the other side of the note, we can speculate that 1/4 of the whole merchant's customer somehow uses bitcoin or even it's not it's fine.
A single customer that used bitcoin as payment method in that store can grab some other bitcoin users too especially if the said store is easy to access for it's co-bitcoin users. Just make sure that bitcoin payment will not be dependable on a third party services but rather own owner's system to somehow save some fees.
That sounds logical. Why wouldn't they just put a payment option for Bitcoin?
Profitable companies (large companies) take direction from consumer demands and react to real (or perceived) consumer complaints.
I haven't bought Adidas in a very long time because they use endangered kangaroo leather. Even though they agreed to stop using it I will never buy their products again. I don't trust them to do the right thing and will not spend my life supervising or researching what they are doing right now.
Companies that refuse to accept Bitcoin or stop accepting Bitcoin (like Microsoft) might see a perceived stigma to accepting it. Silk Road, pirate@40, MtGox, BFL, kidnappings, and other negatives have been hyped by the media to create a general perception of Bitcoin as "crime money". Why (as a decent law abiding citizen) would I shop at a place that gets part of its revenue from "crime money". That's the problem with negative press, it sticks with people a long time and is really hard to wash off.
Good points for sure, negative press is picked up quicker than positive news IMO
especially in todays world where "crime" accounts for a very large portion of news stories
along with politics [mostly negative]
For governments at the moment in general they are not seeing a benefit to their
exchequers from Crypto Curencies so they are all to happy to hear the negative
press except that is Japan who recently recognised Bitcoin as legal payment

Now this is a really positive news story and hopefully in the short term
will see other countries following Japan's stance!
I think if you have a business in Japan the time is right to accept BTC
