It could be but I'm not certain.
What I find interesting is that I don't believe Jane's intention was to necessarily make this a place where extras are available, when she moved here from Roz's place in Connahs Quay.
All the early indications were that she would follow the same style as Roz, offering proper massage with a hint of sensuality.
It's maybe not surprising if business has been slow, but I wonder If Jane's aware of the extent of extras apparently being offered.
Equally important, I wonder what the other girls think If Mona's now getting lots more bookings.
If Mona's to be believed the other girls, or at least some of them, aren't offering extras, and Mona only works part time at the shop.
I wonder If this may be a similar situation that occurred at Rose's place where the girl got sacked.
