Push or Pull

I hate doors that have the sign that says push or pull, if the door requires a sign then the door should either a) open both ways b) have a handle that only allows for it to be opened the certain way (i.e. the bar for push and a handle for pull). Half of the time I do not notice the sign and perform the incorrect action or the sign is facing the other way and I read it backwards and again perform the incorrect action to open the door. That is my random thought for now.
