It's odd, because if this had been someone like Rihanna, ATRL would be all "YASSS BITCH DRAG HER!!!! SNATCH THAT $3 WEAVE!!!!". But because it's Nicki, suddenly everyone has a conscience? Bizarre.
But the real question is, why did the maid go into a room with a Do Not Disturb sign on it? The only thing she has to read day in and day out and she makes a "mistake" when it's Nicki's room? The sign is on the handle, that she has to turn to even open the door.
Nah, bitch wanted in on some action.
Hotel maids work long hours from early in the morning until late at night I'm sure when its easy for them to make mistakes every once in a while when they're busy and have been working for hours (esp at a busy time like christmas), maybe the maid was talking to her colleague or something and opened the door without looking at the door handle.
