Etiquette - is it only for others?

I am seeing daily in many places that people are expecting etiquette from others but do follow on their own.
A bus conductor expects passenger should give respect but he calls everybody in singular.

A man sitting in the bus by our side does not tell us to move when he alights but expects from others.

Everybody expects children should hear elders but no elders hear children

Everybody expects others should say 'good morning,thanks' but not following in their dude
