I noticed that at multiple MRT stations when you take out the toilet roll, you will will see a glory hole and the people in the next cubicle can see what you are doing.
Now MRT station choose to remove all toilet roll and if you are having an emergency, you have no paper to clean up. Some guys in the other cubicle will peep through and look at you doing your business. It is disturbing and better to finish your business quick and go.
They should either patch up the holes or put back the toilet rolls.
