I am not sure if the OP has been to the Tim Hortons in the United States, so here is something you need to know. When my Dad was in Buffalo for some meetings he went to a Tim Hortons there and when you order a coffee they always give it to you in a cup that is one size more then what you had ordered. For example if you were to order a small they give it to you in a medium cup, if you order a medium you get a large cup and if you order a larage they give you an extra large cup. So this means their locations in the United States do things different then any location across Canada when it comes to ordering coffee.
