I went to the McDonalds on 7601 s. Vincennes. I didnt check my order but as I open my burger they put like a cup of raw diced onions on it. I called to let them know they were foul for doing it they hung the phone up now they refuse to answer. I called back to talk to a supervisor or someone in charge and they steady hanging up. If this is how this McDonalds treat a customer that just spent money at their establishment I will definitely place a call to bbb &;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Alderman In the morning. This is not the first time this McDonalds has had rude and unprofessional workers.
