Round the twist
Years ago at work we had water coolers which had a knob which could be turned to set the temperature of the water. In the height of summer, I often found that of the water was actually rather tepid which defeated the object of the cooler. Investigation revealed that one of my colleagues was actually turning the temperature down because he didn’t like the water to be “too cold“.Arguing that he could just let it sit in his glass for a few minutes to warm up fell on deaf ears, so I fixed his little red wagon by the simple expedient of turning the knob to “practically ice”, then pulling it off it’s spindle and replacing it so that it was indicating about midway to ‘room temperature’.
And there it stayed. Apparently the water was the right temperature so long as the little indicator on the knob said so.
