The building's hours and the suite's hours are different documents
Most suite buildings run on assumptions set years ago: services during business hours, lighting on a timer, cleaning at the end of the working day. A suite that has since extended into evenings or Saturdays operates against that background without anybody having revisited it. The building is not doing anything wrong, it is simply running to a pattern nobody has updated. Nobody set out to leave evening patients in a dim lobby; the schedule simply predates them.
Raising it as a specific question tends to work better than raising it as a complaint. The committee can consider a later attendance, a lighting change or a different arrangement if it is presented as a defined proposal with a cost. Presented as general dissatisfaction with the lobby in the evening, it usually produces sympathy and no decision at all. A proposal has a decision attached to it, which is what a committee can actually act on.
