Very good Passenger Elevator Trick !
This is usefull for those who often use elevators !
When we press the floor no. button on the panel lift start moving. But if
someone on the next floor calls the lift the lift stop for them, this
could be very irritating in rush hours !
Now, if you Press the Floor No. Button and the Close Door Button both at
same time then the elevator would not stop for any one in the way and
will stop directly on the destination floor !
** Note in some elevator systems this trick might not work !
