The rule, as people use it
Place works a lot like time. "At" is a point: the spot where something happens, seen from far away. At the door, at the bus stop, at work, at Kenji's place. "On" is a surface: something touching a line or a flat top. On the table, on the wall, on the second floor, on Main Street. "In" is a container: something with sides around it. In the box, in the car, in the kitchen, in Osaka.
The same place can take two words, and that is where the meaning lives. "I'm at the school" says where you are on the map, maybe waiting outside. "I'm in the school" says you are inside the building. When a friend calls and asks where you are, "at" is the usual answer, because they want a location, not a floor plan.
A few fixed ones to learn as they are: on the bus, on the train, on a plane, but in a car and in a taxi. The rough reason is size. If you can stand up and walk around, it's "on".
