Maybe it's just me but that always grated with me a bit. It felt sometimes a bit like a Today programme interview where "presenter style" was the product.
Not to take anything away from the content though. It's the sort of programme the licence fee was made for.
It's not just you, that does grate on me sometimes as well. I get that he needs to move the show on, but I often feel like the guest is trying to make quite an important point when he interrupts. Still love it, though.
