shouldn't your mobile be inside your bag? I noticed most of people here (local or not) are not careful with their belongings. Even in food courts, they leave their bags/phones on the table & go take their orders. For me, that's irresponsible considering that this is a public place. In our country we do mind our own things (unless you're really sick of robbing people). However, maybe Azi has a point if she sound defensive as your tone of story is very subjective to a certain nationality & generalizing the issue to a single incident. Of course, we understand your rant over the matter, but shouldn't you consider also what you post?
On the brighter side, good thing you have found it.
