Slight aside we to at BA enjoyed the 'mess' alongside TBA canteen, table service and alcohol readily available (not free mind). This was eventually closed with the opening of the Hatton Cross club, to which many hundreds adjourned to at Friday lunchtime, in addition to other lunchtimes. The late Lord Marshall closed that down as part of economic cutbacks but also due to many staff not returning to work on a Friday afternoon.
PS; What a dreadful uniform no doubt in 110% polyester!
