Definition of "Laodicean"

The baths were mostly tiled showers, with an endless variety of spouting mechanisms, but with one definitely non-Laodicean characteristic in common, a propensity, while in use, to turn instantly beastly hot or blindingly cold upon you, depending on whether your neighbor turned on his cold or his hot to deprive you of a necessary complement in the shower you had so carefully blended.
