Why why why did the belief develop that repeated pressing of the button on a elevator/photocopier/pedestrian crossing would somehow speed its operation?
It doesn’t.(OK, I know it’s done as a vent for frustration, I’m really gloating about my own patience.)
(And, I guess, a certain stubbornness to NOT to what is clearly so instinctive)
(Besides which, is there any more insidious way to spread contagion than these very focussed hotspots of public contact? How many times do you really want to press your fingertips against them?)
