Locked up

A weird experience this morning when (trying) to leave the hotel. Because there were only 2 guests last night and therefore no hotel staff in the morning I left the key at the empty reception. Left the hotel by the first glass door into this corridor and then the second glass door was closed. Going back didn‘t work, as the first glass door only opens from the inside. Locked up ... and reception reopens at 4 pm ...

There was an attached leaflet with 3 phone numbers. First number ended on a voicebox, second as well. Finally I had a lady on the phone, but she was at home and not in the hotel. Fortunately from nowhere another member of staff passed by and saw me waving. Problem solved.
