okay story telling time. this is as accurate as what mavis told me.

mjc installed this turnstile gate in their school, probably because they see every other school is doing it. the school thinks its damn cool to have it. so they installed it. well done. but the school didnt learn from other schools how to operate this thing well. they have this thing at the sidegate, that has all the other bus services other than 3. the turnstile only turns in one direction, like what you'll see in sa. but the gate beside it is locked after 7.30. so which means you can only exit but cannot enter from that side. then comes another thing that even i dont understand. for each person to exit, he has to press a button once. and only he can exit, so the next person has to press again.

well done jon for this video.
