Maria: (great posture, grinning wide) Welcome to the opal spa, how can I help you today?
Melissa: (annoyed look on her face) can I get a facial
Maria: (smiling) of course, what kind of facial we’re you looking to get today?
Melissa: (rolls eyes) not sure, isn’t that what your here for?
Maria:( smiling) I can definitely help you find out what kind of facial your needing today, I’m just going to ask you a few questions first.
Melissa: (smacks lips and rolls eyes) okay
While Maria keeps herself composed Melissa shows nonverbal communication by her tone of voice and rolling her eyes, smacking her lips. Those are ways you can show you are annoyed or not in a good mood exactly.
