It doesn't pay to piss off your domestic helper.
Because chances are she'll turn around and piss on you ... in a manner of speaking.
An Indonesian helper was given two weeks in the pokey for mixing urine in warm water and serving it to her employer, whom had just given birth, as revenge for the boss's bossiness. That's gross, but at least she wasn't casting spells.
It took the employer several days of browbeating to get the maid to own up to what she'd done. The moment she did, police charged her with two counts of "administration of a noxious thing with the intention to aggravate".
All this because she was aggravated by the administration of obnoxiousness.
