for me... if you want to cut in the queue directly in front of me, ask first and give me a reason why... if i don't accept, you go to the back...

if they simply cut in, i'll tell them politely where the end of the queue is... if they ignore, i will shout loudly for everyone to hear... if still ignore, i'll push them hard, step on their shoes, trip them when the queue start moving, especially on public transport queue...

My personal solution of dealing with queue cutters.

Jump right infront of him/her , thus cutting his/her queue, turn around and ask him/her  "How does that feel ? "

the "Tidak Apa" attitude is whats inside the mentality of most people in malaysia, it cant be helped if the government dont act against it.
