Really? It’s a nice mild, but flavourful coffee. Are you sure you’re not thinking of Starbucks. Vile and vomitous would be adjectives I would connect with Starbucks...plus BURNT.
Being you’re in Canada I don’t know why you would ever venture away from Tim’s.
There is a Tims like 80 miles from here and I’ve thought about going to it. We had one in CT when I used to take long motorcycle rides. I would always stop in for their vanilla “hot smoothie”.
I may also suggest regional differences. When in Ireland, McDonalds is simply my favorite. The food is so damned good. But here ? It’s worse than MREs.
