Anyone who is guilty and watch this and does nothing

In public transports, in MRTs, I have seen alot of situations where old men and women board the bus and do not get a seat. In mrts, alot of people pretend to be asleep just so they do not get ranted at by the commuters to give up their seat. It is very obvious that they are just pretending to sleep as their eyes peer open once in a while, checking whether there were any old people are around. The next time I get a seat in an MRT or bus, I will not hesitate to give it up to an old folk when he/she gets up the public transport
