since when has "networking" with shop owners been of any significant benefit to punters? a few cheap massages or first word of new girls on roster?
additionally any network contacts garnered through shops have limited use as we cannot use them in our genuine business networks.
I personally use my networking activities to develop seriously more significant business than a few cheap massages.
plus being in the circle of shop owners whom may or may not be involved in nefarious activities increases your chances of having your phone tapped. (remember Cloud 9 court transcripts)
consequently for me, in my personal experience, 'networking' with massage shop owners is of little benefit.
I am OK with not being invited to your networking events.
