the roll up the rim to win thing is crap though.  I was driving a cab in fernie, drinking 3-4 coffees a night, 4 days a week and i only one 1 free coffee.  Eventually i just started using my coffee mug again because it was such a waste to try and win..but even then they try to give you an empty cup to roll up.
I also liked the place better when they gave you glassware when you ate in...felt more like a coffee shop then a fast food joint.
