She doesn't seem to 'click' with anyone though. She's just too passive for most folks (certainly for me)
That tallies with my experience too. I've seen her a fair few times over the years and only one of them really stands out as being memorable.
Heather is a good looking girl with a good body (not overly fussed by the augmented boobs mind you) and has always been pleasant enough, if a little shy (or aloof dependant on your take on her). There is nothing wrong with the service she offers, however there is just something a little distant about a punt with her and she doesn't seem to 'click' with anyone from what I can see.
One thing she really does have going for her is she is extremely reliable and an excellent option to have up your sleeve as a plan B punt, but I wouldn't visit for any longer than a half hour. Always a good solid neutral, you're unlikely to skip out the room, but at the same time you'd struggle to rate what you've just experienced as a negative!
