How many restaurants have this in their restrooms?
There is this notion that this sign is for the employees, that it reminds them that “employees must wash hands”. I’m pretty sure that competence is everywhere and that all employees know to wash their hands, before they are employed.
So, why post this sign? Why have this in every restaurant? Because it’s “the theatre of the mind”. It’s the story we tell ourselves, the scene we play in our heads, the message that make us feel comfortable and that is “employees must wash hands”.
