If you start counting microsecond savings, shouldn't you also account for the fact that people looking for a Lobby button in a real elevator (and not on a website) would actually be looking at the bottom of the panel, because that's where a Lobby button typically is. If the button is not there, then a person will have a WTF moment, followed by a mental stumble, followed by a guess that the Lobby is actually on the 2nd floor, followed by time needing to look the panel over and so on. Even if the button is at the bottom, but of a different shape, size or if it has a LOBBY on it, it's still a hassle, because that's not what's expected of it. If you ever been to Vegas with its humongous "Casino Floor" elevator buttons, you should be able to relate to this with ease. The whole thing is basically an http://en.wikipedia.org/wiki/Spherical_cow http://en.wikipedia.org/wiki/Spherical_cow example. It is silly.
