They don't screen calls on Talkin' Sport Bort. You ring up, say you name and give them your number and they ring you back when it is your turn. You can talk on any subject you like and they don't cut you off like the commercial stations do, which I find very irritating. I have only heard Heaps do it a couple of times, I think he cut Adrian off as he was rambling on and some guy the other day who wanted to talk about the Top Gun movie.
The other stations want to know what you want to say and when you've said your bit, that's it, they cut you off and you don't get a chance to say goodbye or thanks. They do say thank you for your call but it is way after they've cut you off. I'm old school as you all know so I find it a bit rude.
