first part: a. I don't really focus on it alot, but if there are places that i know accept bitcoin i will always go there and try them out. But i don't specifically avoid anything else because they dont, and i very often bring it up if there is any opportunity to when i go anywhere.

Second part: c. and then i just use my visa. but i always add a little comment about why btc would be more convenient for me or why they should accept it. Never pushy, just cordial and/or playful. I think being pushy will associate being annoyed with hearing about bitcoin, and I think that works against us. If its just a tool out there that it seems like people are using, then they are more likely to look into it, imo.
