For Sam Nu Snetral my advise is to go late hour say 9.45pm you can park your car along the main road for free for a few minutes or for regular hours take someone along who can wait in the car. It's usually a 10 minute job unless there are long queues.

There have ben cases and times where overzealous Poslaju security guards look out for people who park there and go elsewhere. It can get embarrassing.

Once I actually posted a parcel then wanted to go to CIMB but the guard told me to remove my car after my Poslaju business is done.
