I had a similar experience at [ a large company ] I used to work for. Had a French Press sitting out on my desk, was quite a bit cheaper than getting coffee in the cafeteria. Came in one morning, it was gone and had been replaced with a nasty note from security. Coffee makers were a banned item (due to fire hazard), so that meant that the French Press (as well as pour overs) were also banned, as they are used to make coffee. Rumor has it that they would also confiscate single-serve coffee pouches too.
