I tapped down the hall with my cane and poked the elevator button with the rubber tip. I dislike germs on my finger. Indeed I am making the button germ situation worse with compressed floor dirt, but when there is no one there to see, I do as I like.
When I gimp onto a public elevator, I make a great wobbly show of it. Then I poke my floor button and the “door closed” button repeatedly with the tip of my cane. People look askance, but no one says anything. I’m old and I can get away with it. So I do as I like.
