Been there once. The WG I saw was actually really fit and her pics were accurate (only thing I'd say is her hair was more obviously dyed in person than it was in the photos). However, the service was incredibly lacklustre - WG herself seemed very disinterested - and there was a real conveyor-belt feel to it, including a knock on the door from the madam the moment your time was up. Don't think I would ever go there again.
Take it you mean Marie.
Nothing wrong with a knock at the door if you're overstaying.
If girl has a bad rep for timekeeping then management are right to keep her on track.
You have no entitlement to more time than you paid for nor to delay the next punter.
If the knocking is too loud or the girl abruptly terminates then fair nuff it's a negative.
HoD is a glorified walk-up especially since it started back to backing appointments.
Knocking also happens when you're both making too much noise so it's fair comment if you're scaring the passers-by
