I have also had the same problem with Tina over the years. There have been quite a few times that I have booked with her only to find that she has had to go out, or needs to leave early etc etc. I've usually been substituted with Jo with whom I just don't really click. Whilst I have had many enjoyable times with both Tina and Lisa (before she left) I have also stopped going. I suppose partly because of the above but also because I may have been too many times and got a bit bored with the place.
