Answer:
The managers behavior is an example of ageism when he calls Michael and "old coot" and mocks at him because of his age.
Step-by-step explanation:
Even though it might look impossible it is one of the major reasons for discrimination in our modern society. Ageism is the action of stereotyping and discriminating against someone because of his or her age. It is seen in all scenarios and social levels. But it is more present in the edges of great adulthood and mature adolescence. It is also performed in its majority by young people between the 20s to late 30s. It originates in the misconception that someone can't do or be something because of his or her age.
