The pics could be taken on different days, the fact that the Starbucks and Old Navy are close by only mean that both stores are within the same area.
If the pics are legit pics and not set up, then that means they were all likely taken in the same area considering if she was seen in one area on a particular day the photog would have gone and watched for her in that same area the next day and so on...
I understand that it's been narrowed down to both places being in the same area, but I do believe that this photographer was either invited by the DT or was someone from the DT and that FCA was posing and made money from these outings.
