It’s time to guess what this red illuminated button does! Based on the icon, what do you think?
My first guess is “turns a fan on and off,” but let me introduce the context to help.
This makes me less sure about the fan idea. What else could it be indicating? And, should I be worried that it was illuminated the entire time I was in the elevator without having been pushed by the occupant (it was only me in there)?
