Yes but most JT's arnt quick enough to consider that when you say it to wind them up. Especially right after they spout off about being real techies.
Mate, if all you have is 'I have Senior in my acting rank and you have Junior in your real rank' then that is a bit crap?
Fact is, most (all?) of the remaining JTs are from that abortion that was the Mech/Mech, Mech/Tech system anyway, and they were pretty much handed it to them on a plate just like you.
