The Picard ManeuverYes, but
wallybeavisAs everyone has already said, use the paper towels. Some doors are also equiped with a small piece of metal at the base of the door which you step on, and pull with your shoe
That foot thing is an awful design IMO. Rather than a step-on to pull, it should be a design that allows you to flex your foot up and hook it under something to pull. The step-on kind necessarily requires you to put weight on it, letting off pressure on your other foot thereby causing instability. This can be difficult to manage for other people or on doors requiring a heavier pull force to open. The hook under kind would stabilize the person trying to open the door.
Counter argument: having to hook your foot runs the risk of damaging the tops of your shoes (often softer material) or your foot if you’re wearing sandals. You can be sure that the bottoms of everyone’s shoes are designed for at least minimal impact protection.
I like the foot step and use them when I can, but it helps to reinforce that the paper towel with a well-placed trash can is the best method imo.
