They should remove all the signs that SAYS RESERVED....I have sat, Mass Rapid Trains, in Malaysia, Taipei, Hong Kong & Bangkok...they do have signs that give seats to.......but not signs that says RESERVED for....
Hard to tell, who is above 55....some of the older ones DEMAND seats & Pregnant woman too....& some with wobbly legs...we must have survival guide when we take trains, after all we pay for seats too...to identify those above 55 deserve a seat, pregnant woman...no need to ask if she is pregnant...if she is wear short, she turn or bend a bit, you see stretch marks..she is pregnant...the belly, round smooth & with an even shape, pregnant...the rest are just belly bump of fats...
Anyway...it our wish , manners & education to give up our seats to anybody...not to have people dictating or imposing on us.....it is my wish to give up my seat to you,..if you are old, pregnant etc..
If one is very old & walking wobbly...or woman with belly so big, that the baby look like it is coming out any minute or just with a big belly...should not travel on public transport....they are a health & public menace..
