This sums up soaps.
I have something really confidential to tell you. NO ONE can know about this.
Oh right.
Yeah, so I'm thinking let's meet in the busy pub to discuss the really confidential thing.
Emm, okaaaay. What's it about?
Joe Bloggs, I think he murdered Mary Smith.
But ... doesn't he regularly drink in there?
Yeah, and we might end up needing to sit in the booth directly beside his usual booth, depends how busy it is.
But ... might he not hear us discussing him?
Possibly, however I still think it's thee best place to discuss this highly confidential thing.
Or the folk who are skint but pop into the pub for a drink, take a teeny weeny sip then leave, leaving 98% of their expensive drink not drank
