Unacceptable behaviour, I nearly booked a duo that day too but decided to save some money and went to see another SP instead. Glad I didn't bother.
What I will say is this. Tori and Aimy seem to work the same days, 2 days a week for around 5-6 hours a day. I would imagine they would easily get booked up by regulars in that timeframe and end up fucking off any new bookings.
Shit way of doing business, but they all do it. I've been on the receiving end which is always shit, but when an SP bumps another client coz she wants to see you instead, it is a

moment.
