Do people really use these things in this way? Do people really bow honorably before this machine to get hot air on their heads? I become too self conscious and paranoid in public restrooms to dare do such a thing. Even if I could think of a logical context in which it would occur to me to try this I wouldn’t do it. But why would you? Did you just wash your hair in the sink? I admit I’ve been forced to use automatic sinks fussy enough that the only way to get a useful amount of water would be to place a head sized object before their sensors, but that doesn’t mean I’m going to.

That is, I presume the lower glyph is meant to represent a person’s head, disembodied or not, and I presume the finger-print/stove-top burner design is meant to represent the disembodied head’s hair. Another question would surely be who is short enough to be able to get their heads into this position. The drying apparatuses tend to float maybe about three feet off the ground. You’d either have to be a small child, who I’d recommend get out of this room as fast as possible regardless of how wet your hair is…though now that I think of it you wouldn’t be tall enough to reach the sink, meaning your hair would only likely be wet if someone had dropped you in the toilet, in which event, again, I’m telling you to get out of there as fast as possible and tell the police. So either you’re really short or you truly have decapitated someone, someone with wet hair, that you want dry, which at last explains why the head pictured is not attached to anything.
