I only visited once. I had about half of a Tim Hortons cappuccino left when I went in. I sat down and started to look at the menu. I was the only guest in the whole restaurant. The server (owner?) approached me and told me I had to leave because he "didn't know what was in the cup" that clearly said Tim Hortons on the side. I understand that a place might not want outside food because it might negatively affect sales, but for one I only ever order water to drink when I'm at a restaurant, and two; I had planned on ordering to go. I was pretty put off by how rudely I was treated, told him it was "no wonder the place is empty" and vowed never to return. He acted as though I had a cupful of acid that I was going to throw at his face when really I just didn't want my cappuccino to get cold while I ordered and waited for food. As the only guest in the whole place, he could've easily let it go. But instead he treated me with disrespect (choice of words and tone of voice) and lost a customer forever.
