housekeeping 正名房務部. 係酒店入面既簡寫係 HSKP. 點解叫房口? 如果你留意下, 執房 D 人一定將架車泊左係房門口 ka ma. 一來等個客知道有人執緊佢間房.二來防止他人進入房間嘛.一陣個客 D 野比人偷左就唔好啦.用黎防竊賊既其中一招黎 ka. 咁架車成日頂住係房門口嘛.整整下咪叫左做房口 lor.
Because long long time ago, the housekeeping department was operated from a counter/window (main responsibilities were for the distribution/collection of linen and toiletaries item. Since this encounter/window looks like a mouth, so people started to call it as "房口".
