In my experiences at SC if you have seen a girl a couple of times those "unicorn" type extras are on offer. Your milage may vary but I have had some fan fucking tastic times with a few girls there over the years.
Odd un offers the goodies straight off the bat but heaps don't.
around 12:30 AM they update the list of girls available to work. Which ever girls you will see on nz website list at night time 12:30 am - 01:00 am that girl will surely work next day.I recommend texting the girls[Manager have the phone bdw] around 9:00 AM- 10 am to confirm what time girl is available according to your timings and how long you'd like to book for. By 11:00 AM, many of them get booked up quickly, as they usually only work a few days a week. If the girl you're interested in is already booked, you may not get a response to your text.
And Jaz only work Thursday and Friday 12:00- 17:00
