Free numbers from the same engine the full planner runs. Pro turns them into the exact order per product, cocktail ingredients, glassware and one shopping list.
Those 4037 serves do not arrive evenly: the opening hour is the fastest, about 931 serves, because every guest wants a first drink at once; over hour 2 the bar settles into a steady 777 serves an hour; through hours 3–4 the pace eases to around 776 an hour as the crowd winds down; through hour 5 the pace eases to around 777 an hour as the crowd winds down. The totals above already carry this curve, so the bar is stocked for the surge, not for the average.
Field note: the garnish fruit is always on the order
Whatever the menu, Green Jar ships 2–4 kg of lemons and 3–5 kg of oranges with every bar, scaled to attendance. A bar without cut fruit reads as understocked long before any bottle actually runs out, so the fruit never waits for a cocktail list to justify it.
