some people (20%?) will arrive later to the conference venue if they need to get food first (30-60m later if you incl. transport, buying, eating outside the venue etc.). for those people, they might have had either 1-1s or casual conversations over breakfast.
some people (10?) might be more tired or have a less good experience if they come early but don’t have time to get breakfast (so it’s not really buying hours, but quality-adjust hours?)
some people (1%? 5%?) might come in much later if they know there won’t be food til lunch
