People Love Their Coffee

I think I'll keep this short:
This morning while I was walking along Richmond Street to get to work, I walked past a Tim Horton's. It's usually typically busy. Today however, there was a line outside of the door. Is there some kind of promotion going on like Roll Up the Rim or something? I don't drink coffee, so I don't go to Tim's that often so I don't know. I just thought it was interesting.
