I saw the first few minutes of this before The Archers and I thought she sounded very odd, like a smug hostess greeting a social inferior. Most peculiar. I have it back on and am not near the remote whilst typing this so can hear her cackling away in the background. As said above, a false laugh. Is it cos GC knows more about the items than she does so she has to change her style? Doubt it, so it is a mystery.
But then does anyone know the weather forecast? I heard her say at 7.00 that we should rush to buy the Dyson fan because it will be 30C this weekend. Really? I have been perished all day here in London and 30C seems a bit of a change within a week.
Just editing to add I reckon she is just trying to make herself the biggest personality on-screen. Ghastly old bat.
