Maybe their (grand)kid. They looked over 60 years old.

I think i read somewhere they are running an awareness program, but don't know the details. 

In any event, I've visited those shops specifically coz they were on btcmaps. Otherwise, would have bought the ukulele in ABC store downstairs the hotel. So it pays to activate it.

Is that square thingy only activated in the US?

yes, i am curious about that. I wonder if Square terminals had a pop up or something on an update. I do think they sent out an email about it. Or I wonder if he was someone who heard about it in the news and decided to go for it.

Yes, both this one and the previous one use square. But afaik, they still have to activate it, so her husband must have done something.
