chicken in the vegetarian meal

Last Wednesday, I had a work meeting at the wimpy in beacon bay, I ordered the vegetarian breakfast as I am fasting, I still told the waitress, please insure that the kitchen knows I am not eating any meat at all, including eggs, ... after a quite few bites, I realised that something was not right, I then looked at the veggie fingers thinking maybe they had put in the wrong thing, but that was fine, I carried on eating, but again I could faste something wasn't right, I then looked through the mushrooms as that was the last thing I ate , and there were chicken pieces in it, I called the manager , she apologised and asked if she could bring me something else, ...... what do you say? What do you do in that case? ... Does wimpy not care about us customers that are fasting? Why offer \VEGETARIAN
