I don't like Tim Horton's coffee, but it's always been more of a social thing to me anyhow. During my first year of University, I spent many evenings writing papers, drinking [strike] sludge [/strike] coffee, and people-watching. I do this less at Tim Horton's now, because I no longer live near a 24 hour shop, but it does hold a special place in my heart.
It is a place that McDonald's can never steal.
