politeness

Hola.
Do you come across this situation?
1. When you Q to pay your groceries, suddenly a stranger ramp in and is served before you.
2. At the ATM, the stranger behind you providing no space, Q near that you can hear he/she breathing.

Its unacceptable!
Speechless when this impoliteness are create by an adult.
Sad if this impoliteness are perform by hijab wearing ladies and mature men.
Intolerable if this impoliteness are shown by parents.

Why can't human beings practice respect?

Note:

Children seldom misquote you. In fact, they usually repeat word for word what you shouldn't have said.
