Question, every Apple store I've ever seen is crazy crowded all day, do you frequently re-adjust screens durning the day (I've never seen you do that) or is this just a start of the day trick?
Tend to do general tidying all throughout the day. Its normally if you walk past and nobody is using it/requires attention then just straighten it up a little bit. There is no set time during the day where everyone adjusts the display though.
