Me too! Love grocery, tougher with kids. I find the free cookie at the bakery seems to be a good incentive for them to behave, ymmv

In Australia, one major grocery chain has fruit baskets at the entrance for children to choose an item from, for free. Apples, bananas, pears, etc. It's brilliant and many parents specifically pick this chain because of it. The piece of fruit keeps the child from complaining about hunger (usually they're bored or angling for a fun snack instead of being overly hungry) or begging for a treat.
