Well, snide comments aside. Clearly you are the one with the handicap.
Like i said, anyone on that bus can pickpocket you at any stage and time. Doesnt have to be right in front of the guard, EXACTLY where the guard is standing and EXACTLY when you are getting off.
Similarly, if you are carrying alot, boarding a bus is tough. But clearing customs? Really? i have never had a problem clearing customs even with a full backpack and plastic bags on either hands. I do not see your reference here.
Lastly, if you want to be pedantic about KSL to JB sentral, stick to your bus rides and i will have my cab rides. At least i am aware it would be comfortable, clean and safe. Less competition that would drive up the surge in the area anyway.
