Number 1 in bullshiat that is... All the MRT stations in other countries have toilet roll in cubicles. The whole point of that is so that when one needs to use it after defecating. But take a look at this almost idiot level bullshiat reply from SMRT.
How in the world does that save toilet paper? In contrast, people will pull out more toilet paper as they cannot gauge how much they will use and rather pull out more and throw in around later than pull less and have no toilet paper to use.
