Absolutely spot on.  

I have dealt with a lot of merchants before and the general sentiment from these merchants are that the coins being spend are not sufficient to heighten their interest to support it. They have to make changes to their payment system to accommodate for Bitcoin payments and they have to train their staff and this is costing them time and money.

A week ago I visited a local tyre fitment centre and I noticed that they removed the "Bitcoin accepted" sign from their display window. I queried this decision and the manager told me that they simply did not get enough Bitcoin business to justify the effort to support it.    

We should still support Bitcoin merchants, even if the Bitcoin price is low or more of this will happen.
