The apartment across the hall props open our locked lobby door for food deliveries. How do I object without policing them?

A rubber doorstop has started appearing under our building’s lobby door after dinner.

The first time I removed it, I assumed a mover had forgotten it. The next night it was back. Last Thursday I saw the resident across the hall place it there while tracking a food delivery on his phone.

He told me drivers have trouble with the call box, so he props the door for ten or fifteen minutes. He stays upstairs and retrieves the order when the app says it has arrived. From his perspective, the doorstop prevents missed calls and cold food.

From mine, it leaves a locked entrance open to anyone walking by. Our building has eight apartments and no front desk. Packages sit inside the lobby, and residents sometimes let children wait there for rides. I chose the building partly because the outer door locks.

I said, “Could you wait downstairs instead?” He laughed lightly and said, “It’s only while the driver is coming.” Then he went upstairs and left the door open.

I removed the stop after his order arrived. We have not discussed it again, but I now check the lobby whenever I hear the door. I dislike becoming watchful inside my own building. I also dislike the idea of photographing him or sending a complaint to management before making one clear request.

The complication is that the call box truly is unreliable. Visitors sometimes cannot reach us, and delivery drivers leave. That maintenance problem deserves fixing. It does not make an unlocked lobby an acceptable workaround for everyone, at least not to me.

I am considering sending him a short message and copying the landlord separately about the call box: “Please do not prop the lobby door. If you are expecting a delivery, meet the driver or let them in when they arrive.” The landlord message would ask for repair without naming him unless the behavior continues.

Would that sequence be fair, or has the first conversation already happened? Should this be handled resident-to-resident, by building management, or both at once? I want the secure door to function as intended without turning a neighbor’s dinner habit into a personal feud.
