Dear Prudence,
I work in a small office with a limited staff, and we can hear literally everything that happens from our work spaces. A new colleague has the most unfortunate bathroom experiences every day. From our desks we can hear every sound. It also smells, and sometimes she leaves leftovers behind. She bought air freshener, so she must be aware there’s something going on. Can I say something? Maybe post a note to flush twice? It is so uncomfortable and I am so grossed out I try to avoid that bathroom at all costs, sometimes holding my pee all day until I can run across the parking lot to the building next door and use the public restrooms in the lobby.
