I like: how in depth you went with your observation! I like how you went down all these different isles and didn’t just observe people, but also the snacks they have! Nice!
I wish: that maybe for your experiment you would have done a different place than your observation so that then there would have been a cool contrast between the two!
What if: you would have staked out by one aisle for a while at target? That might have been an interesting thing to see!
