No Slacking

This is rather amusing to see. Recently on the Singapore based webpage www.stomp.com.sg, there was an updated on the new signages on board the Singapore's subway trains. "No Slacking" ! Wonder if this was just a prank or was it for real? You can't even slack and relax on you way to home from work? Overwork at job/School and even whilst traveling on trains you have to behave diligent, Stiff and serious?
