Her wording she has a normal job, is a bit crap too. 
There is nothing wrong in being an escort.
There's enough girls out there, that do this full time.
The irony is, when she puts her green light up, she's willing to put her and other punters + other escorts health at risk, for an extra £50.00. 
Her wording should be, I have a full time job away from this, or something like that.
Can't quite believe I'm about to defend a BB'er, not about doing BB or the OP's Negative which is fully deserved. But she doesn't say or even infer that there is anything wrong with being an escort.
Yes, she says she has a normal job, it is you that has taken that as a negative. The full sentence on her profile is,
"I will only be taking bookings occasionally as I have a normal job and this is more fun and it will only be a couple of days a week at most"
Also how do you know that her other job is full time? So that might be factually incorrect. IMHO the way you have chosen to interpret the actual words says more about you and how you think about escorts.
Plenty say on their profile that they have other jobs and do this part time because they enjoy it, which is how I would have interpreted what she said.
