Notwithstanding their in-it-together NAAFI Wagon image from WW2, which suited the era, they were due to go. While they were wrongly compared to American facilities - which are subsidised - they were never dynamic despite an often captive audience, and preferred instead to rely on their heritage, and monopoly with a typically unenthusiastic and complacent staff.
When I was at Leeming their response to the popular all ranks bar threatening their market was to toady off to the hierarchy and have the all ranks bars' hours restricted, as opposed to actually making an effort to attract punters. Saw a similar pattern elsewhere over the years.
