If you want to see all the ladies in a turn shop then you have to ask.
if you go to a shop that does lineups like the one at Villawood i think its 27 Christina road from memory and there other shop down the road at 67 I think then you can get to see all the girls that are available.
Personally I prefer the shops where the girls are introduced to you one at a time, that way you can ask them a question if you wish, they however may not understand depending on their knowledge of English.
