I do take your point, U&D, and I may well be wrong, but I suspect most touring Thai girls inherit a local manager according to where they're located. So this was meant as a warning more about the location, rather than the girl herself. I've had the 'landlord's here to fix something' story often enough to know that the only sensible response is to fuck off and forget it.
You have way more experience than me in this market but I think some of the “managers” oversee their bookings and accommodation and then have a list of charges. Charges for booking accommodation, setting up AW & VS profiles, per booking, even responding to text messages. (I think it depends on the package the girl wants and needs)
From my limited experience of mainly reading reviews the ghosting, switching, double booking issues seem to follow the girls around rather than be location based.
