Sands is not open until 4pm on Sundays. So I can only assume her dad works there and he stopped by the closed club for something with his daughter in tow. Or maybe they didn't go all the way in and they were hanging out in the entryway but the door is locked so they were just standing in the covered door area outside the club.
Either way. Seeing a little girl walk out of a strip club is not something you see everyday.
