Lift etiquette

If you're only going up or down one floor, why take the lift? Especially in a busy building with only 2 slow lifts. It's just lazy and annoying. In the case of the building I'm referring to, it's usually much quicker to walk up the stairs 1 or 2 floors than to wait for the lift.

Of course, exceptions exist if you happen to have a disability, or you have large, bulky, or heavy objects to transport, or there are not any nearby stairs, such as in the building R lives in.
