Overwhelmed, and as it is also a medical centre the kid might have been feeling unwell to start with. I’ve broken down in tears at the chemist as an adult when I was feeling unwell, so I can definitely sympathise.

His Mum was managing to distract him for brief periods and he’d be all smiles for a short period, then the whole situation would dawn on him again and he would be on the floor wailing. I expect a long nap will be in his future and hopefully his afternoon is better than his morning was.
