lost count.
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.
"let them nag the merchant". That means you get the staff to ask the merchant to accept crypto?
yes. when merchants see staff get tipped it gets them curious especially with handcash or cointext. I've been surprised at how many people 'know' about crypto &have always wanted some.
