I should try this at my local cafe

Dog buys treats for himself using leaves as money.
I'm impressed that he figured it out for himself, apparently.

I'd have to use a maple leaf because calculating the exchange rate for foreign currency is too hard to deal with just for a cup of coffee.

That is one smart dog!!

Very cool,!!

It didn't work.
I tried a maple leaf and a dandelion leaf.
Neither was accepted.

The dandelion leaf did look a bit strange. Maybe she thought it was counterfeit.
