• Make some noises!!
  

They recommend when you enter the cubicle to poo poo, during the "critical moment", start coughing loudly so that people will not hear the "poo poo" noise! Haha, they also recommend bringing in newspaper so that you can rustle the newspaper to make noise during the "critical moment" too...

• Remain anonymous
  

It will be embarrassing for you if your poo poo is smelly and people know that you are the culprit! I also feel uneasy poo-poo-ing in public toilet...Thus, they teach us methods to remain anonymous..

You can either

1) only enter a toilet with nobody inside..However, I think it's quite difficult because it's out of your control and it's impossible to wait if you are extremely urgent..haha...

2) wait until everyone is out before you come out of your cubicle..haha..I do that in my office!! haha..that way, no one will know who the culprit is... hee hee
