i hate cold weather

I got a cup of hot tea at the deli at work today (cause it's freezing cold in the mornings! *sob* ) and got a Canadian nickel back as part of my change. Just a few months ago, the same thing happened with a Canadian penny. And while getting foreign coins as part of your change isn't that unusual, I suppose...after all TX is a bordering state, right? Why is it, then, that the only non-american change I've ever gotten is Canadian?!?

You'd think I'd get centavos, or something. O.o
