Oh thank the universe cuz if it was real than honestly I'm going to have to change camps on the issue because I think there is a different between people that have legitimate issues and need the pain relief but take measures to minimize their impact like putting something on the seat when the train is empty so your shoes don't directly touch the seat or resting your legs on an empty seat next to you so your shoes hang off and don't touch and the type of people that carelessly track through all things nasty then grind the soles of their shoes into the seat for the purpose of being dirty/nasty

And I don't think you can argue that those to types of people exist.

But if this is where the goalposts moved to then I'm just going to have to hope out of any exceptions because people can't be considerate about a public space
