School teacher asks her pupils to brush their teeth with sand

Someone Witnessed this teacher at a school somewhere in Badagry asked her pupils to use sand to brush their teeth as punishment. He confronted her but the lady refused to stop. How pathetic is this?  He didn’t say the name of the school but said it’s somewhere in Badagry if anyone knows it. The schoolname is Zino Great Academy. See more photos BELOW: (source from DAILY MAIL)
