Being accused as a teacher, of being a potential kiddy fiddler wasn't a welcome experience, so I used a pen camera with the full co-operation of the school's owner to protect myself from any further potential accusations.
What would you have done? Argue with your vindictive Thai accuser that you were replacing? Wait to be set up? Hope for the best? Walk away from the job?
Don't be daft.
I still use a covert camera, it's very handy, especially dealing with dodgy customers like you.
Now piss off troll.
