What I do now is tip staff, let them nag the merchant.
The area I live has many backpackers, once they hear they can use it when they go 'home' they want it.
Much easier.
Cool! I actually did this at a meetup once. Then I saw a VLOG #3 by Roger Ver, where I says he will give a tip in Bitcoin Cash. Pretty awesome idea!
responses have surprised me, particularly young girls.. one "oh yeah my friend has been trading for a while, she loves it" Me, "well, you can show her this new wallet" *B I G* SMILE.
