1. Revolving Doors. I get that they are eco-green or whatever. The fact is, they scare the bejeebus out of me. I mean, completely. Did I get stuck in one as a child? Knowing my brother, this is a real possibility. But...why do they have to put big signs on the non-revolvers, so it looks like if you open them the emergency bells will sound, when, in fact, they will not.
2. Auto-toilets. These drive me irrationally crazy. They never seem to work well. I still have to touch the flush button have the time. And, unless they have auto-everything else (sink, soap dispenser, paper towel dispenser....), there is nothing more sanitary about it.
But the revolving doors...it's almost embarrassing.
