How on earth did she manage to ring the buzzer?
Yesterday I was sat on the balcony outside my hotel room when the buzzer sounded, signalling that someone was at the door. As I approached the door it opened and the cleaner entered. Naturally I beckoned her in and said that it was no problem, then put on my shoes and went out to allow her to continue undisturbed.
There seemed to be nothing unusual in this, until later in the day when I suddenly noticed that there was no buzzer press on the door. I was rather curious where the buzzer was secreted and ended up checking all around the door.
Despite checking the walls all around the doorway and even the outer rim of the door frame I am unable to locate a buzzer anywhere. I even went to the extremes of checking on the wall facing the door, but to no avail.
I am at a total loss to understand how she managed to ring an imaginary buzzer.
