I don't know that it's a common "modern ritual," but quite a few years back the pretense used by a certain young lady - who shall be nameless but whose intitials might be LiK - was that she wanted to come up to my place to see my software.

Almost anything that suggests a "common interest" is probably a fair shot as a way of "getting acquainted." The hazard might be that she really might have had some microphones of which she was very proud, and it was just an interest-in-common and was a competely innocent offer.

In your case, it's most likely that the invitation to see her microphones was just a sneaky and underhanded ploy, and her real nefarious intent was to get your advice on how to setup the balance on the Behringers (were they the mixers or just amps? - it could mean either in my area).

She quite probably just wanted to use you for your (assumed) superior knowledge as an elder and more sophisticated gentleman.
