First instance:
Hunter leg restraint garters got a bit worn so went to stores to get another pair - only to find that they only had one in stock! On further investigation, I was informed that they came in packs of three!
Second instance:
Second day after the Argentine invasion of the Falklands, I went to stores to draw a shoulder-holster for my personal piece, only to be informed that these were “war stocks” and couldn’t be issued. Small outburst remedied that!
Last (and most amazing) instance:
As the task force headed south in 1982, all stores requests for units involved became category 1 - ie get them there asap! A couple of weeks into the conflict a gert great box arrived on board Invincible containing a brand new ASW sonar. Unfortunately this could only be fitted when the ship was in dry dock because it was below the waterline. Resulted in a large, expensive splash!
