That's exactly where most of the wear comes from.

I once had a conversations with a painter at a university. They do the women's bathrooms every year whereas they do the men's as needed. Women have nails and rigs and purses with metal hardware and big fancy buttons and clasps and stuff on their jackets.

I wouldn't be surprised if subway wear on the back wall is gonna be dominated by people carrying things. People carrying things tend to filter there because you can put them down beside you more securely and a lot of those people already have backpacks so it's nice to lean against the wall.
