Tim Hortons review: service

I recently went to Tim Hortons for a coffee. As has happened a few times in the past, going thru the drive through, they only filled my cup about 3/4 full. I decided this time to ask them politely to top off the coffee. When I got the coffee back and stirred it I noticed grounds floating around. I have never had grounds in my coffee there. I can only think that they did this to "pay me back" for asking them to top it off. If this is what I can expect when saying something then I really question the training of the employees. I am adding pictures of the cup and it's contents. I would appreciate hearing back from you about this issue. Thank you. I can be reached at [protected]@icloud.com
