As a fellow neighbor, we are already aware of the fast track lane 😂 technically, even the fast track lane also needs to queue nowadays because of the amount of people choose to fast track. Instead of 45 minutes clear the customs, paying 200B probably get you there in 40 minutes though 😂 I mean, if you're the one who's paying, you'll probably tell yourself "luckily I've paid, otherwise I will be there for another 2 hours".
