Two things that suck about being a Canadian in the US:
1. Self-service gas pumps never work properly because they invariably want a US postal code to validate the credit card.
2. 1-800 numbers don’t work. I felt this today when I tried to recharge the parking meter in the absence of quarters. (Vancouver, like many US cities, let’s you deposit money to meters remotely over the phone. Awesome idea, with this minor flaw).
