Forgive me for posting here as I have never had any connection with the services.
I have read this thread through all the way and still don't quite get it - when we come in contact how exactly do you want me to treat you?
I can obviously only speak for myself but I would treat you in the same way as I would treat anyone else I met for the first time that is to say I work on on the assumption that you are a normal reasonably courteous human beings until proved otherwise.
I am perfectly happy to acknowledge that to the best of my knowledge most service personnel do a highly professional job and do it very well given the equipment they have to work with. I do not let the memory of the bunch of close cropped rowdy youths who kicked in nearly every panel of my car without provocation one Saturday night in Warminster many years ago colour my attitude, there are always some that give a bad name to a vast majority of well behaved people.
