A crack head must have been working and fucked it up.
Thing about Tim Hortons coffee is I don't think there is anything special about the beans themselves, they just make it correctly. I can't recall mine ever being fucked up.
McDonalds coffee is fine but they are 100% guaranteed to fuck it up if you're in the drive thru.
Here in Reno the Peppermill and Atlantis have good coffee shops, but I am at GSR and it has a starbucks and it blows. And I am hardly gonna go out of my way or anything, I don't even like getting coffee at places which don't have drive thru.
Tim Hortons also gives you a donut or muffin with the meal. So you get coffee, sandwhich, and one of them. Tim Hortons is awesome. I am sure I could eat enough to get sick of it if I had some around me but that would be a good thing.
