Answer:
Illusory correlation
Explanation:
Illusory correlation is a psychological phenomenon of sensing a correlation or relationship between a particular quantity and other variables however unrelated the two variables may be. A person may establish such connections, which are indeed false connections, as a result of over emphasis on novel incidents that are easily noticed due to them being salient
For example, when a waiter at a restaurant is being rude to a person after the person was made to walk under a ladder due to ongoing construction.
