What I like in Singapore is that they are serious in posting all informational stickers. This is to remind their citizens and visitors about the restrictions on each of their properties.
This time, I was riding the MRT and thought to take a photo of one of their reminders regarding the MRT reserved seats.
When you enter the MRT car, you must be aware that the first two seats, usually in dark blue colors, are for those people listed below:
Aunties and Uncles (old folks),
Person with Children
If you know that you're strong enough to stand for an hour, give your seats to the needy. A smile from their faces means a lot for you as you reach your destination. Like this... :)
