A couple of years ago, I went to a place here in Vancouver called Mystique (as far as I know, there's still an agency at that location but it's now called French Kiss or something like that). They didn't physically have the ladies line up for me but they had me wait in a small lounge type room and each of the 4 ladies that were on that night came in to introduce herself briefly. Then the madame returned and asked which of the ladies, if any, I would be interested in. I think they did something similar at BBC when that was still around. I was there on two occasions but that was to see a specific lady who I called ahead to book, so I didn't experience the "line-up" there. At the Fox Den, you definitely have to book ahead to see the lady in whom you're interested. And while I have not yet been to spa540, from what I've read I thought that they also did the "brief introduction" thing.
