Final answer:
Chantal is likely experiencing job burnout characterized by emotional exhaustion, depersonalization, and diminished personal accomplishment often experienced by individuals in human service professions.
Step-by-step explanation:
Chantal is likely experiencing job burnout, which is common in human service jobs like serving in a restaurant. This phenomenon is characterized by three dimensions: emotional exhaustion, depersonalization, and diminished personal accomplishment. Emotional exhaustion refers to the feeling of being emotionally drained, depersonalization leads to a detached attitude towards service recipients, and diminished personal accomplishment pertains to negative evaluation of one's work and contributions.
Given that Chantal no longer enjoys interacting with people, which is a core component of her job as a server, she may be developing a sense of depersonalization, leading her to a detached and perhaps cynical attitude towards the customers. To prevent further emotional strain and potential health issues related to chronic hostility and stress at work, it would be beneficial for her to evaluate her situation and consider strategies to combat or cope with job burnout.
