You folk stuck on the "the customer is king" mantra are still missing the point. Yes the CUSTOMER is KING, but the OP was not a customer - he was an enquirer who was looking at several alternative schools. You do not inconvenience your paying customers or disrupt productive activities to entertain an unknown enquirer. Sure, rudeness is unacceptable and a polite welcome should be the order of the day - if it was inconvenient to deal with the OP at that time then making a revised appointment to meet later would have been a good idea.
