Three groups with different expectations
Residents judge the building by how it looks at seven in the morning and at ten at night. Commercial occupiers judge it during business hours and care about the entry their clients use. Visitors notice the lift and the lobby. Those expectations do not conflict often, but when they do the cleaner is left choosing between them without any basis for the decision and no way to explain the choice afterwards to whoever was disappointed by it.
The lobby is usually where it surfaces. A shared entry that serves both uses gets heavy traffic across a long day, and the timing that suits one group is wrong for the other. Ask each provider how they would schedule a shared entry serving both, since the answer requires them to have thought about the building rather than the floor area and their proposal will show whether they have serviced one before.
