My local Starbucks in Calgary is part of a cashless trial. For the first week or two they were allowing people to top up Starbucks cards by cash but they don't allow that either now. Personally I love it as the amount of people who used to pay with change drives me crazy! It's almost as annoying as the people who wait till they get to the checkout to find their purse/wallet. (There is a special place in hell for those people!)
