This is really a good idea to let people know about cryptocurrencies and bitcoin, It's really a smart move to even ask if they're accepting bitcoin or not, because if they don't know about it, then in the most of times they will ask and you'll get their attention about bitcoin, so if he knows about it, he probably tell someone else and then it will be a loop, so bitcoin will be spread so quick in the whole country which it will gain more popularity and a lot of people will join this community so quick.
