Advertisement that pissed you off
(OK, I know the image sucks. But I have to make it quick before the SMRT staff saw me taking photos and start questioning me as if I'm a terrorist planning to blow up the train station with these photos. Anyway, it's a picture of a MRT train window.)
The MRT window is there for a reason. It's for you to see which stop are you at if you didn't catch the PA announcement (Cause the cabin is too noisy or the PA is too soft).
When you block 1/3 of the freaking window, you only cause inconvenience to the audience that you are targetting. That is not a very good way to convince people in buying your products.
