Tim Hortons review: ice capp

I purchased 3 ice caps on my visit to this location. It's inside an esso gas station. They were training a new employee. I placed my order and waited for it. when i got my ice caps, i took them and left the location as i was in rush to get to work. I had a sip of it and realized there was funny taste. not sure what it was, but tasted like the milk or cream or whatever they use had spoiled. i wouldn't recommend this location to anyone not just for this reason, but they were messing up other people's orders too and had some employee's relatives in there talking to them in their language.
This was on Aug 24, 2019 around 10:45am.
I would like to be compensated for the spoiled drinks i was served.

thank you,
