The TV Standing Spot
Over time, the more people walk or stand on something, the more likely it is marks will appear. This especially rings true if it’s a place people stand day in and day out, for years and years. Meteorologists always stand in this exact spot at the TV station. You can see the difference where they did stand and never stood. At least the entire floor didn’t cave in. If they want to get rid of those marks, they’ll have to do some serious scrubbing and cleaning, though it seems like a good souvenir to keep from over the years (How to Clean Stuff).
