An Interesting Elevator

So I was in UiTM Shah Alam yesterday for a seminar. I found the most fascinating thing in the Faculty of Pharmacy. There are no control panels in the elevators.

Inside the elevator - check it out man, no control panel to press 'which floor'.

Ta daa, the control panel is outside!

So ah, you're supposed to press the floor number from outside, and see the screen at the top of the panel? They let you know which elevator to ride. Got A B C D elevators, when you press the number, the screen will show 'A' or otherwise. Then you wait there lor.

Interesting, an anomaly but impractical.
