Input: Third visit to the Flamingo,first two were wonderful. Desk staff on last visit was a nightmare, Casandra seemed to take pride in her rude ,bulling attitude. I don't know if she treat all seniors this way, but we insulted. For some reason she thinks if your hair is grey it is ok to treat us as second class persons, who's credit card she controls.

Flamingo shame on you, your front house staff is the worst I have ever had to deal with.
Output:
NEGATIVE
