I strongly believe that good habits must be taught & cultivated from young. As the Chinese saying goes : it's easier to change & shape a mountain than to change a person's attitude & behaviour.
Till today, I have not seen
a parent ever teach their kids to return trays after their meals at public
eating places.
If you are a parent, I would
like to ask you : Why not ? What is stopping you ?
My parents and schools never
taught me to return trays at hawker centres & public eating places. Only
the army did. But I continue to do it.
Even sometimes, the auntie
cleaner would scold me for doing it. I don't know why. I just smiled at her,
shut my ears & walked away.
It never bother me.
