BBC Breakfast's Naga Munchetty snapped 'that's patronising' at a stunned guest as they were forced to apologise in a tense interview.
Naga, 48, was back on the BBC Breakfast sofa for the first time this week alongside co-host Charlie Stayt.
The pair covered a range of topics during the programme and at one point were joined in the studio by guest to discuss the shortage in medications which has been hitting the headlines.
As well as medications for asthma, ADHD and diabetes, it has now been revealed that drugs that help treat epilepsy are also in short supply.
Naga and Charlie were joined by Claire Pelham, Chief Executive of the Epilepsy Society, and Thorrun Govind, a pharmacist and healthcare lawyer.

Claire revealed that in the run up to Brexit, manufacturers agreed to have a six-week rolling supply so that they never ran out of medication.
She added: "What we suspect, it's a suspicion, not evidence, is that they've reverted to just in time delivery now."
Claire felt this decision was taken because it's the cheaper option before being asked what people should do now if they are impacted by the shortages.
She said: "For the individual person, the most important thing is not to become stressed and to try and keep calm and plan ahead."
But Naga jumped straight in and said: "And that sounds patronising in some ways."
Claire immediately apologised, replying "Sorry, sorry" as Naga continued to speak, saying: "No but I want to kind of aid with this.
"The reason you do this is because stress and anxiety can be a trigger".
Claire nodded in agreement and said: "Exactly, the last thing we want is the anxiety about the shortage to initiate a seizure for somebody which might mean they lose their driving license and affect their life in so many ways.
"So there's help and support on our helpline and it's really important to plan ahead, make sure you give yourself at least a week from prescription in hand to when your tablets run out."
Health news is of particular importance to Naga after she opened up about her own battles last year.

The journalist was diagnosed with adenomyosis, a condition that affects the tissues that line the womb.
People with this condition suffer immense pain as the endometrial tissue grows into the muscular wall of the womb, instead of just lining the uterus.
Speaking about her crippling condition on BBC Radio 5, she said: "Right now as I sit here talking to you, I am in pain. Constant, nagging pain."
She then added: "Every so often the pain changes; it becomes a stabbing pain. A pain that takes my breath away and I can do nothing but sit with it for a minute or curl up to cope."
BBC Breakfast airs daily from 6am on BBC One and BBC iPlayer.
