RENURPP's comment
"the prettiest flight attendant is requested to come aside and take part in the Trace detection."
struck a particularly familiar tone with me.
Last Tuesday (15 Mar) I was waiting to board my flight at MCY when it became very apparent to me that the "rent a thug" doing the Trace thingy was selecting 7 or 8 females for his activities to only 1 male. He was also "patting them down" as well using the back of his hand. This would not have been obvious to the individual passengers but it most certainly was to me sitting in the lounge. He leaves himself open to charges of least inappropriate behaviour, maybe even harassment.
I will be taking this up with the airport in question.
