The technical vocabulary of hotel housekeeping is more extensive than most people realise before they start the job. Turndown service, do not disturb, deep clean, stayover, checkout room — these terms have precise meanings that determine how a room is treated, when it's cleaned, and what goes in it. Getting them wrong has consequences: a room that should have been a checkout gets treated as a stayover, and a guest arrives to find the previous occupant's belongings still there. This exercise drills the vocabulary that prevents those mistakes — the specific language of room status and cleaning procedure that experienced housekeeping staff know automatically, and that new staff need to know before their first solo shift.
