I told her its very unusual she had an interview type process in place for bookings to which she replied she wanted to make sure a person was not a creep or dangerous to her since she could not let anyone in her place (for sex) until she got all the information to her satisfaction from them (not sure how she can identify a dangerous punter).
I am pretty sure either she had a bad experience with someone and or she was interested to know more about her punters.
WGs certainly have different vetting procedures and I understand why they have them, for their own safety and if it makes them more comfortable accepting a booking then that's a good thing...

Description by text I doubt they could glean much from, and whilst phone call could be a better indicator of how someone comes across through the way they speak and tone its obviously still not fool proof...
Farquar from lemmington Spa could come across really polite on the phone, turn up, and be a total prick... Wee Johnny fae Easterhoose might sound like a Ned but be brand new in person, who knows...
One thing I will add, some WGs may request a call before booking though if they've had previous issues with a punter(stalking etc) as they may recognise the voice... Not saying that's the case with the WG in this thread, just in general...
