Krispy Kreme ROOLS! Haven't seen one of those for years, though.
I had Tim's bits once, but ... (any number of really stupid, not particularly funny comments regarding his wife, the police, medical procedures or a weasel named 'Pascal' omitted for reasons of taste.)
Seriously, I always stop at Tim's, but rarely get anything because the lines are always long. I leave feeling deprived, but I've never been all that attracted to donuts, rolling or otherwise.
