Shock at sugar consumption

I took 4yr old DGD to the cinema yesterday. In the ticket queue aisle, at her height, were sweets and sugary drinks galore.
She asked and I said no, I had brought a drink and snack, but the child in front was being bought a fluorescent green smoothie and a huge tub of sweets. DGD eyes were as big as the saucery eyes of Elsa and Ana, animated heroines of the Disney film we were about to see, but all she said was " I like smoothies"

It makes me very cross, especially today when I hear the big companies are still at it with the dangerous levels of sugar in food and drinks. Why? Don't their managers have children?
