It could also be randomly getting a cup of coffee from a coffee maker that's due to be cleaned out, and has old oil residue in it. I remember being disgusted when I was in the wardroom of the carrier my father was assigned to, and happened to see, through the door to the galley, that the cooks had one of the big coffee urns unstrapped from the bulkhead, and one of the mess techs was scraping several months' accumulation of congealed coffee oils off the inside of the urn with a spatula... Put me off Navy coffee for years.
