Thanks, I would've bailed after 5-10 mins for an unknown.
Typically if I'm given the Cloisters as the venue then I'll try to find a Plan B (and C) in the block before I make the journey.
There are plenty of active SPs in the Cloisters though usually it's newish girls so it's more likely you'll be ToFTT than finding a well reviewed one known to UKP.
