David and Rita could be absolutely smashing pals, or he could even become her next daughter.
He certainly ticks several boxes.
Firstly he's used to dealing with old ladies, because nobody under 70 ever goes in the Salon unless they actually live on the street, so all those years of dealing with Mrs Buttercupfanny, Mrs Elderberryhedge and Mrs Honeysucklegusset will have stood him in extremely good stead.
He'd be on her level so to speak from the off.
Secondly, Rita likes nothing more than sitting in judgement on people, frowning at their antics, and looking down on them in the most disappointed, disapproving manner imaginable.
David would give her endless scope to indulge in this because he's a right little shyte.
Lastly, David doesn't eat home-cooked meals, he's always seen coming out of the Chippy or the Kebab shop stuffing his weasel face with some greasy snack or other.
Rita meanwhile loathes cooking, she's usually too pissed to cook - plus her kitchen cupboards only have bottles of Gin in them.
So again, they'd fit together seamlessly.
David also likes Vera Lynn records and free money.
