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 5733 serves do not arrive evenly: the opening hour is the fastest, about 1110 serves, because every guest wants a first drink at once; over hour 2 the bar settles into a steady 924 serves an hour; through hours 3–5 the pace eases to around 925 an hour as the crowd winds down; through hour 6 the pace eases to around 924 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.
