As an inspector I do not consider a break room with only a microwave oven a kitchen. The definition of a kitchen was relocated from 210.8(B) to Article 100 in the 2008 Code. The inspector should be familiar with the wording, and what is meant by permanent facilities for food preperation and cooking.
If anything the inspector should look at 210.8(B)(5) for any receptacles located within 6 feet of a sink.
If it isn't a kitchen and it isn't near a sink then no GFI.
