(The app - Timestamp - takes terrible pictures.)
My only difficulty was getting clear shots of the deli case. Part of this was because the app was terrible. It was definitely the hardest in Publix. Employees were stocking product all around it, and the employee working the deli was really good at her job. She watched everyone that came near and asked if they needed assistance. I had a really hard time getting close enough to get a shot. The slicer and the scale were also right beside the case, so her back was never to me.
