Three disruptions this morning at POFQ, all with the "room occupied" sign on, we checked in last night.
Around 9:15 the housekeeper knocked, I was in my pj's working and my dd (tired college student) was sleeping. I opened the door as much as the latch would allow and asked her to please return later. She was quite rude and said "open that door and speak to me properly"! - So I unlatched the door and in my PJ's opened the door enough to say (in what I think was a very calm voice!) do you see this sign it means we are still using the room, can you come back after 11? She said yes and left.
20 Minutes later a gentleman came and knocked, sign still on the door and offered us a return customer gift and yes he said he had to give it to me right now. It was a card with a bottle of eyeglass cleaner.
Finally about 30 minutes later another person from housekeeping knocked and asked if we were having problems with the safe.
The housekeeper was rude, the gentleman with the gift was kind of goofy (in a good way) and the housekeeper asking about the safe seemed confused. Nobody asked to enter the room.
On our way out we stopped at the front desk to leave my comments and fix my MB that didn't open the door. The manager told me that none of the above cast members were supposed to knock when the Room Occupied sign was out and that all the "floor managers" would be spoken to. She said they are doing security checks but those would be obvious, they would be dressed like security or managers and they are the only people authorized to knock when the RO sign was out.
So that's my report - I hope I don't have any more this trip!
