To be fair, Kalamazoo isn't exactly a desolate station with zero services that leaves everyone to their own devices. It is an intermodal station that also hosts the city's bus system (Metro Transit) and Greyhound/Indian Trails.
There are at least 3-4 non-Amtrak staff members around at all times, from early morning to late evening, and the police maintain a presence after dark. The station also has a cafe, vending machines, nice bathroom facilities, and plenty of benches. I have personally witnessed the Greyhound/Indian Trails and Metro Transit staff answer questions about Amtrak once the Amtrak window has closed. I have no doubt they can answer basic questions posed by a first-time traveler.
