Tim Hortons

I went to this location this morning at 9am. The customer service was terrible. I just wanted an empty cup for my extra large coffee and they refused to give it to me. The manager was also rude and said next time I come there they wont serve me. She refused to give me back my money. The manager told me to go back to India. I go to Tim Hortons everyday and Ive never been treated like this before. I highly dont recommend this place.
