If I were king...
In this health conscious era when we've all become germophobes I still cannot figure out why we don't have regulations regarding restroom doors. It makes no sense for the doors to open inwards. You come in with (presumably) germy hands, get them even germier in the restroom, wash them thoroughly and then have to grasp the door handle and PULL to get out and you KNOW that you are probably one in 100 people who wash their hands properly.
If there are paper towels handy this is a problem that can be solved by simply using one to pull the door open with but in restrooms with only blow driers you have no choice but to touch the handle.
No, I'm not ridiculously concerned with bacteria and viruses but I do think that it would be so damned obvious that restroom doors need to have their hinges reversed so that we can PUSH the stupid thing open with our elbows, shoulders, hip, feet, whatever.
