Let's say one lift is breaking down, ppls r going to rush to get the other 2 lifts. This situation is rather annoying.
when u stay high floor, u got no choice, but wait for the lift
When u stay lower floor, u may juz use the staircase as an option.

Since the security system in 1120 park avenue using the access card for lift taking.

Imagine, when u r ordering gas. From a high floor unit, u gonna wait for the lift and take the lift to reach the G floor to bring the Person up to your house. Tis is juz an example,
