I haven't won anything yet, but then I don't go to Tim's often. There's one in the cafeteria of the college where I take one course (two mornings a week) but there's usually a line-up out the door, and the caf coffee isn't any worse with no line-up.

Krispy Kreme is the bomb, and my BMI is thankful there's only one location in BC. When we visited New Orleans a few years ago we'd stop in to get a doughnut and they'd hand us a fresh one free.

Also, I must try this some year:
