airport toilet doors, resturant menu no1 germs

What is it was Australian airports ... why the toilet entry doors !!! Modern airports seem to have walk in and out toilets where no need to pull open a door that 2000 other people have used that day, and how many have really washed their hands !! and the Airline lounges are the same ..
Worst offender is the restaurant menu .. ewhhhh
