Answer: Problem Recognition
Explanation:
There are several stages a customer has to go through before he finally makes the decision to purchase a product. The first of these stages is the problem recognition stage.
Problem Recognition entails that the consumer identifies a void that should be filled. There is an abnormality which results in discomfort and must be corrected.
This is what happens in the case of Jerome who has dirty dishes. Not having his favorite dish washing liquid, is a problem which he identifies. This informs his decision to go to the corner store and purchase a new one.
