Receptionist (The Husbands of River Song)

A receptionist worked at a restaurant by the Singing Towers  on the planet Darillium. The Twelfth Doctor was indirectly responsible for creating her job, as he was the one who inspired the existence of the restaurant by giving Alphonse the idea to build it in the past.

The receptionist set up an appointment for the Doctor at Alphonse's restaurant when he asked for a table on the balcony with a view of the towers, putting into motion his long-delayed date with River Song on Darillium. However, the receptionist indicated the restaurant was fully booked until Christmas Day in four years' time. The Doctor happily agreed to this appointment, using the TARDIS to skip the wait.

Four years later, the older receptionist, who by now was sporting a new hairstyle, directed River to her table on the balcony, where the Doctor was waiting for her. When River asked if they had a good table, the receptionist replied that it was "the finest in all the galaxy". River took a moment so she could use her special outfit-transforming perfume to change clothes for her date, then continued to the balcony as the receptionist left. (TV: The Husbands of River Song)
