Public washrooms: we used to have simple sink taps that you could open with a handle.
Now you’ve got some high-tech gizmo that’s supposed to detect your hands waving around and automatically turn on the water ... but half the time it doesn’t work
What was wrong with simple taps?
This one bothers me too. And even when they do work, the water is always COLD and never hot. How are we supposed to control infectious diseases or kill human waste germs if it is always cold? In fact they violate health codes in probably every municipality. Most require business bathrooms to have hot running water to wash with or shut the doors and not operate at all, especially every business that serves food.
Just remember, the dirty hands always touch the handles. Even after you was your hands you reach out touch the dirty handles to turn the water off.
The cost of the water and sewer services. It’s free to you to wash your hands or flush the toilet, but it cost a business or government agency money to provide that “free service”.
