I think the people who clean the subway have one of the most futile jobs in the world. Then there are the people who MOP the subway platform. Because of how fruitless the situation looked I felt bad standing anywhere she had finished mopping despite it being a very busy platform.
I suppose it’s doing something, but it wouldn’t feel very good to do because the platform still looks exactly the same. The woman I saw mopping didn’t even have her mop bucket anywhere in site so it looked like the mop was barely moist. If I had a choice I’d rather be the one using the high powered water hose thing to clean the platform with.
