An entire family was not wearing their masks, were chewing gum, and coughing at the airport. When saying something about it, I was told "What's wrong with you" and called a "[censored]". Upon asking to the personnel where to go to report this family, I was sent to various places, ending up at a desk that was unmanned. Nobody could apparently help me "I'm sorry". This is unacceptable, that people can get away with this behavior and continue it. It is also unacceptable that there is no department to report this to so that this can get enforced right away when it was 'accidentally missed' (TSA certainly didn't say anything about it).
