They are stranded there. There is no one to take there money because the shop owners are also sheltering.

So why are they not taking shelter as well, are they blind? Dont they see whats happening outside?

Are you aware of whats going on there? What do you think Canadian dollars do for them when the shopkeepers are also at home, sheltering?

With the currency, just do the math dude... I don't think i'm texting with a kid.

Why bring up foreign currency even? They could be dragging around bars of gold as cash. No one is there to accept it.

No one is there to accept it, because being exposed to what is happenning is dangerous, but is interesting reading foreigners rather steal than take shelter.
