That doesn't work in a toilet stall.

May I suggest some fiber?

Every time! The coffee shop by my old house had motion sensing lights in the washroom, and every damned time I would be plunged into darkness half-way through my visit... Urgh.

Our company has this in the toilets, when it goes dark you just wave your hands

Ours does too, but there's no sensors inside the stall... You can wave all you want, there's no way to turn the lights back on without opening the stall door.

Thank goodness for phone flashlights!
