Logic suggests unlikely. There was another Viet girl (not Jessie) worked in Artarmon that fits the exact description, in fact I think they used the same description. If Alice/Sarah were to return to ml it would make sense she do it in her own shops where she would take all the profit rather than just a cut, plus she would have a backlog of regulars who would be there in a minute and she would be booked out straight away, she could pick and choose which days and times etc. Of course it well may be her and she has her reasons, but my money is on that it is the other girl.
Having said that I'm a shit gambler so now I've said that it will be her...��

I should add I'm pretty sure (not 100%) she was at Cremorne on Friday when I was there..
