I wonder if you're talking about the launcher for managed classic Mac workgroups, At Ease. I have an almost identical experience to you, including the coffee machine (though more of a closet than an office).
Eventually our folks replaced At Ease with some other app, (Cyber something, control something? no idea) but they setup a hotkey to disable it which was nothing less than shift + K. That didn't last long at all, with Karla, Kyle, Keith, and Katie getting incredibly frustrated just trying to type their name.
