Yes. Thats the most important part. If theres only ARRIVAL chop and no DEPARTURE chop, I bet the next trip to JB would be a "costly" one.
I always mention that I have MACS.
A few times I accidentally mention even to the Singapore customs but most of them prefer KFC.
But twice happened recently, because now no need white card, the Malaysian side still chop my passport.
One sheepishly wrote VOID over the arrival chop, while the second customs officer apologised profusedly until I paiseh and tell him small matter all it cost me was a little space on my passport page.
As long as got valid MACS, but still kena chop then you are in the clear and not your fault.
But if no MACS but past ARRIVAL chop still lonely bachelor, then get ready for naked squats while they put on latex gloves..
