After you talk to Tabitha (Dixon's niece) during lunch day go with her to the burrito's stand. Next day go to the same stand alone and the two workers will prank you with a hammer. After that you will have some inner thoughts about it and Tabitha and you'll ask yourself whe she will call you about the photoshoot. Come back to the office and you'll receive her call.On the 1st day talk to Dixon's "niece" who works nearby.
her brother is a photography student.
It is supposed to be on the 2nd day, but I couldnt trigger the event.
I must have missed something.
