Currently at the Hampton Inn Wilmington Downtown. I was in the bathroom when the door to the room opened and someone walked in. I said "hello?" and a woman said "oh sorry I was just checking on something" and left. I called the front desk and was told that it was the assistant housekeeper who wasn't aware I'd checked in and was making sure the room had towels and hangars. It was hard even getting an apology out of them and it wasn't until I told them how startling it was they finally did apologize.
