Let's talk about value today.
What is value? How do you value value?
Well, something of value to me may not be something of value to you...
..meaning you may pay a high price for a beautiful painting but you need to pay me for me to keep it. I do not know how to appreciate the value of painting thus, any paintings looks the same to me
Therefore, who is to set the value of my personal stuff? Me right?
You may only guess the value, but definately will not get it right..
Now, let's look at this sticker:

If everything I carry... is valuable to me... can I carried all my belongings with me and not check them in when I fly with MAS?
..and I wonder, why is there a need to label the baggage, inside and outside if you are going to hand carried them with you!
...somemore.. you need to lock it!
Is it that bad...meaning you will be rob during a flight?
Well, guess I will carry a knife or get a gun somewhere for self protection the next time I catch a flight!
