Ah! Put on some shoes! Not only it is not safe, it is not hygienic. I also don’t like seeing you rub your bare feet on the equipment. Especially since I also noticed you don’t wipe those parts of the machine down when you are done.
Also when you bought your gym membership, I know you signed the same contract I did and that contract includes an agreement to wear appropriate workout attire. Appropriate workout attire includes actual closed toe/closed healed shoes not nasty old beach sandals that keep falling off your feet.
