I tried to get a pop from a vending machine at our resort and I had the nerve to try and throw the machine off by sneaking in one Canadian nickel (I really had no idea it was there). Needless to say it kept returning it to me!
That is such a good question and one I never would have thought of asking. I could just see me down there in Aug w/ my bag full of Cdn quarters, yelling at the damn washing machine for not working.
I have to do my laundry at a laundromat here in Canada on occassion and this is not an outrageous cost... pretty much "average". Some places I go, it costs $3 to wash, $0.25 per 3 minutes of drying time.
