A President

A president is a citizen, first and last. As a result, as a president, the citizen receives what is due any citizen: social courtesy and contempt if contempt is earned or respect if respect is earned. This isn't the Middle Ages where nobility no matter the rank was given respect worthy or not. A president is a citizen among citizen peers elected into office to perform the role's responsibilities described in the Constitution, and when the term of that role concludes to resume whatever role performed before or any role to be chosen. The president is just a citizen and is always just a citizen.
