Just a simple thank you

I just got back from Tesco with my mother.
I am seriously annoyed with some Malaysian who just dont know how to say thank you.

Why is it so hard?
Seriously bro, you wont lose anything by saying thank you.
In fact, it makes you look pretty well educated.

For example:
1. There's this one lady who asked for more stock of rice. That poor worker when all the way just to find you another pack of rick and you take it, walk away, showing any sign of appreciation.
Aiyo lady!
I know that he's a worker but that's his job.
But do you know that it's very easy for him to say lie to you by saying that they have run out of stock,
and save him all the trouble.
A simple smile would make him fell that what he have done is worth it.

2. There's this one kid who picked up an apple that fell from this man's trolley,
and he didn't even say thank you.
Why?
because you're older?
because when you say thank you that kid wont respect you any more?
There's no such thing la deyy.
Maybe for you it is not a big thing, but you are actually injecting a virus in our culture. There are a big tendency that the kid will grew up being like you. Disable in showing appreciation.
 So, at your age, you should have known better, be wise :)

A simple smile would do,
but a simple thank you wouldn't hurt too :)

Or at least, do this :)
