Chipotle Mexican Grill

I am a regular customer at Chipotle in the downtown Brooklyn area and Kings Plaza in Brooklyn. Today I decided to visit the location located at 474 Fulton Street, Brooklyn, NY 11201. What mistake...I order two chaiken burrito and requested the salad dressing be poured into my burritos. Instead I was given a lecture about cross contamination and lecture about other branches doing the wrong thing. So, please tell me this should I be concerned about my health because the other location been pouring the salad dressing over my burritos? A Chipotle employee was the person who recommended me order this way and guess what I loved it! I'm used to get great customer service but today was not the case.
