I agree! Some of the worst presentations are when someone is a "big fan" of the product or range, and assumes others feel the same way. If you are watching to learn about new products you do need that impartial extraction of information from the guest. Dale is extremely good at this. Even on shows where he does have more expertise, he is still good at doing that. He trumps Julia in doing his job as a generalist salesperson (Julia does get a bit cosy and exclusive on some shows, but is untouchable on giving clothing sizes and fabric composition).
Now - can anybody tell me - do Dale, or Charlie for that matter, ever present Richard Jackson's Garden? I can't remember if I've ever seen them doing a show.
I switched on a week or so back and it was Charlie and Richard Jackson!
