I have tried most of the major shopping Mall in KL ...always gotten the attention of the Security guards but they always stop in mid-sentences(wish I record / videotaped those events )....Always be polite and they will really ask a lot of question (like why no smell ?and where's the smoke? and why no fire?..all the definition of smoking is absent..and they can't prosecute you for that!) but they'll let you go on your way without a bother(the penalty in Malaysia is RM 5000= US$1612 if caught smoking in Banned Areas)...In fact some of them are my trial patients now...good eh? Anyone had experiences like these? ..care to share...?
