The term civil service covers a vast array of individuals and roles, its a tad harsh to tar them all with the accusation of being lazy, because of one individual, particularly as that person i imagine worked quite hard to juggle all those roles This specific individual certainly looks to have been taking the micky a touch and if the targets were being hit it does suggest the targets were on the lax side for sure, but I can't deny a small amount of respect for the front of the person

No. There are plenty of BSS examiners not GSR. Currently, the line is that only boats used for 'domestic' purposes (i.e. liveaboards) need a GSR examiner to carry out "work" on the gas system. Work being anything involving tools such as disturbing a tighteness test nipple. A non-GSR BSS inspector can do a BSS even on a liveaboard if the boat has a bubble tester fitted.
