Several moons ago, my mate and I had booked over the phone, 2 girls whom we had seen previously, but when we arrived neither was available.
Despite our protestations, she said wait, they'll be out shortly.
So we did, the first girl that was free, she'd pushed to my mate despite being a different girl to what was booked.
As we had waited long enough, my mate agreed to go with her, when he'd finished after a 1/2 hr session, she was presented to me as the 2nd girl I had booked, seemingly not knowing or had forgotten that was my mate I went with and I had seen who he had.

We walked out there and then.
Nasty PoS, never went back.
