The Boss of the Lunch Hall Returns!

Lori: Josie, I had hardly finished my lunch when a lady told me to "Go away!"
Josie: What? Why? Mummy! Did you hear this?

I followed up with some enquiries...

Me: Is she a teacher?
Lori: No
Me: Is she a dinner lady?
Lori: No
Me: Is she a learning assistant?
Lori: No.
Me: Then who is she?
Lori: I don't know. She wears pink and purple.
Me: Could it be the boss of the lunch hall?

I said this jokingly. Josie used to complain about her heavy-handed lunch hall tactics when she was in P1. One day, she just disappeared, never to return.

Lori: Yes!
Josie: Yes! It is the exact same person as the lady who was the boss who used to put me in trouble.

Who is the mysterious boss? What role do they play in the school?

Nobody knows...nobody knows...
