I saw her maybe 2 years ago (maybe more?), she was using the Jamie name but was based in a flat in Hatfield. A bit like the OP I was told to park in a specific place in the huge empty car park, and once left alone in the bedroom I pushed up the blind to see that she had wanted me to park in that area so she could see me walk across the car park! Thank Christ I didn't scratch my arse.
Anyway, from what I remember, reasonable/average punt. Good athletic body but liked the sound of her own voice. Nothing stands out as exceptional. Wouldn't/didn't return.
