gallie: I face these idiots everyday. Some idiot uni students will put their bag on the chair, or worse yet, the seat next to them is empty and they still buay zi dong when the whole bus is full, never move aside to let someone else sit! Usually I will give that person my dirtiest look--almost always works.
Once I was waiting for 96 and when it came, the whole front was crowded but the back was empty! And people were refusing to move to the back, so I walked to the back door which was open and yelled into the bus, "Will you all move your fat arses and shift to the back so that others can get on? F---ing morons!" Then they slowly start moving in. IDIOTS.
But anyway, to tell a nice story, I was on the MRT one day, train was slightly crowded, and a pregnant lady got on. An old man gave up his seat for her, which she took. Then a young man gave up his seat for the old man. =) It's always nice to see that happen.
