Should the pieces and the ad spend be handled together?

Yes, if the person running the spend has not seen the dish and the person making the photo does not know which shift is empty. They do not need to be joined if someone at the venue already decides both and only publishing is left. Say who chooses the photo and who switches the ad on. The photo is of one dish and the ad offers another, and neither person saw it. One person responsible for the photo and the ad, with the shift written down.
