Have flown in and out of LBA many times, there is one female controller who does throw her teddy out if you call her ma'am I know of certain pilots who do it on purpose to see the reaction. There is also another female ATCO who calls us sir which I do not agree with, I would rather she gets her left from her right sorted out before calling us sir. I do not have a knighthood and therefore do not want to be called sir.
