I have met many female screeners and LTSOs at EWR, as well as a few managers. I must say that the majority of the females I have encountered at EWR over the past few years appear to have some sort of attitude issue. (And as a female I have most likely received patdowns more often from females at EWR than you - assuming of course from your name that you are male!) The times I have however asked for a manager I was actually pleased with the outcome.
