I've met her a few times, and she's a fit lady and a fabulous all-hole fuck so it's worth persevering IMO.
In my experience she affects a bit of a 'school ma'am' attitude in early meetings - I also was directed to a particular street corner the first time but as it was raining I moved before calling her and stood under a bus stop. I also got 'told off' but actually it came across to me as someone teasing rather than chastising for real. Likewise she once called me out for counting my money out as I walked up the stairs to her flat, even though no one was there to see (except her, clearly!). I reckon it's just part of her character she adopts for this, as those who've met her will know she doesn't hold back on being absolutely filthy in her suggestions about what you might do to her.
