Radio Button

"Turn plastic knob (radio button) left for open"
"Turn plastic knob (radio button) right for close"

This was a label over the shower spigot at a La Quinta hotel in Scottsdale, AZ. My guess from the poor grammar is that it's a bad translation from the native language of whatever nation manufactured the shower knob. If it  turns its a dial, if you push it, its a button. their nomenclature is reversed. If you think about it, radio dials sort of went out of style when we moved definitively to digital displays.

Regardless, It was a let down, when I turned the button, there was no radio audible whatsoever.
