Chipotle Mexican Grill

Hi! First, I would like to say that I love chipotle and I go about 3 times a week. I have always had amazing service and I have never had a problem before.
Tonight, I ordered food for me and my sister. In my food, I found some short black hairs in my food and my sister had some avocado rinds in her guac. I just wanted to make this complaint to let someone know that they should be more responsible and focused on what they are doing when preparing food for others.
Thank you.
