This shop has a policy of giving each girl an equal chance of seeing customers - so whoever answers the door is who is 'next' to service a customer. They're not too keen on letting you see a lineup!
Different story if you've made a booking ... You get who you booked, and they honour your booking (unlike some shops)
Hana was my 'go to' girl for a few years! I must've seen her a good 30-35 times, at 24 Auburn & elsewhere. She's lovely!
