McDonald's is miles ahead of Tim Hortons in terms of their coffee.
I voted for home, but if I go out it is either an independent coffee bar (1-2 times a month) or McDonald's (when someone offers to buy me coffee, or I am buying for the group 1-2 times a month).
I had to give up Timmie's because it was making me very sick with cramps, gas and other issues. I thought I had Lactose problems and then ended up finding it out it was the Timmie's 3-4 times a week. Nice though: saving myself about $600-750 a year not going to Timmie's (just skipping a coffee mid day at all, not spending on a substitution) and plan to spend some of that at Wolverine Supplies very soon!!!
