If an establishment exists to serve "the customer" and if this establishment ONLY exists because it holds and item or service that is wanted by "the customer", then it must also be true that the customer is always right, no matter how strange a request could be, for if the establishment fails to provide something that the customer wants, then there will be no buying, therefore no selling, erego no establishment.
This can also be said of school when comparing administrations to the students. If the school is established for students, then is it not the teachers and other representitives of the administration who only exist
because of the students? Should it not be them (the students) who are most often asked their opinion?
It bothers me that these tend to be common inverses of things that exist for (and only because of) the [usually] subservient person.
