Hold that elevator!

On a recent research trip I stayed at the Holiday Inn in downtown Fresno, CA. The hotel was unremarkably average — clean and functional, if a little worn around the edges (a little like Fresno itself). There was one thing that struck me as unique — the elevators; specifically, their buttons. I've been in quite a few elevators over the years, but this was a first for me. The elevators had 4 buttons to control the doors: Two to close and two to open the doors.

One guess is that this arrangement was the result of a mistake, extra holes were filled with extra buttons for an expedient solution.

But, I prefer to think that this arrangement was the result of a heated argument about the iconography of the buttons — one person preferred the versions with a central line, the other held their ground that the non-lined versions were clearer. After weeks of argument, they broke the stalemate with this solution, "Let the user decide!" As a user in this circumstance, I can only say "Ouch!" Trying to keep the door open for someone approaching was a painful experience, and don't get me started on the PB, PG & 2R buttons.

What do you all think? How did this happen? And have you seen examples of elevator madness? (If you have pictures, send them to me, and I'll collect the best in a follow-up post.)
