Man what a nightmare. I’m so sorry for everyone involved. I’m big on the Howie Mandel train of thought when it comes to touching public surfaces. Elevator buttons, hand rails, restroom handles, escalator handrails, door handles, etc. Use your elbow; a portion of your knuckle, a piece of your shirt; the corner of a credit card; a pen …… things like that. Hell I’ll even ask someone else to press the elevator button LOL. If restrooms don’t have a trash can by the exit door (a lot do these days), use a piece of tissue or hand towel to open the door and drop it on the floor. I’ll risk being a litterbug in lieu of grabbing a door handle then going back to my lunch table and enjoying my french fries 🤷🏽.
