Union thing.......
Follow Me ( Sigame etc...) are mainly a union thing/hangover from our socialist past ( and present ? ).
Many is the time that we have negotiated the highways and byeways of many fine 'dromes after landing , only to find the Follow Me waiting on the centreline to the stand which then drives all of 50 metres on to the stand , and sometimes ( if we are very lucky ) wave their bats until you stop . This often happens even if the guidance system is on !!
Very useful they are , hoping to get a job like that when my medical finally runs out.....................
