Be careful when you are walking alone, waiting for your ride or even when you are inside a jeepney.
My officemate was mugged three weeks ago when he was walking on his way to the jeepney stop. Three teenagers (as he describe it) came from behind, mugged him and took his bag containing all his IDs, wallet, keys and money.
After two or three days, he (or my other officemate) witnessed someone's bag snatched.
A month before that, another officemate's bag was snatched by someone who was pretending to be a passenger. The jeepney driver stopped, was thinking that he was a passenger, then when the guy was about to ride the jeepney, he snatched my officemate's bag. Poor officemate, (s)he lost his/her wallet, IDs, 2 mobile phones and most importantly, his-her make up kit.
Lesson learned: we really don't know when and where we are safe. So we just really have to be extra careful ALWAYS.
