These ideas came to me whenever I took MRT. Inside the MRT shows the signs of giving seats to the elderly, pregnant, handicap and with child. The MRT also has no signs of food, drinks and durians. Why not to have the sign for people being polite in their behaviours? Since Singapore news mentioned about some uncaring public behaviours at http://singaporeseen.stomp.com.sg/stomp/3552/107754/468500, I design these sign posts using Adobe Photoshop after sketching it.
