Can you run Instagram yourself without losing sales?

Yes, when the volume fits after close: a few pieces of your own, stories of the menu and a chat you answer yourself during the shift. No, if posting pulls you off the pass or the pieces go out the next day with a dish that has already run out, because that is when tables are lost. For one week, note how long the menu, the photo and the reply take, and compare that with the real gap between services. The owner promises to do it themselves and the profile goes quiet in the busiest weeks, which are the weeks that needed telling. A minimum scheme for doing it in-house, or a handover to an external calendar if the trial week ate the close.
