Very little kids fly for free.
Young kids get into movies for free.
Students get student discounts.
Military personnel get discounts (which they totally deserve; god bless them)
I just saw a sign today announcing that students get 5% off everything every day between Sept. 1 and May 30 at a particular vendor in this college town. I don't begrudge them that perk. God knows I used to be a poor student.
Businesses offer discounts for reasons of their bottom line (or to build goodwill with a certain group).
I don't see why I shouldn't take advantage of "senior" discounts when they are offered. It's not like seniors are the
only group getting occasional discounts.
