the doors without a lock (washroom, conference, baby's ...)

everytime i go into a mall's restroom, i hate it very much if their washrooms have a knob or similars which i need to TOUCH it, in odrer to open the door,after using the facilities. The least i can accept is just to push the door by my ankle or using my body to push the doors, rather than to use my just-cleaned-hands to touch the knob! And sometimes i feel very annoyed or even disguised which needs me to turn the knob and push, in odrer to enter the room! Is the washroom a very important room needs a lock or knob to make it "so secure" ? And after i finished the matter in toilet, i also need to pass the narrow long way, and then to open the rest mall's doors, to go back to the mall !!  i know that's the kind of doors to make it  a barrier to keep the mall's air-con 's temperature,  but i hate doors, too many doors to block my way, which needs my cleaned hands to touch any of these public facilities or utilities !! And absolutely nonsense, how could those interior designer or architect doing such kind of stupid design and NOT FOR people's convenience? So infra-red water taps is one of the good design and convenient to the user, though it's a bit expensive, compared with the usual water-tap!
