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 2639 serves do not arrive evenly: the opening hour is the fastest, about 754 serves, because every guest wants a first drink at once; over hour 2 the bar settles into a steady 628 serves an hour; through hour 3 the pace eases to around 629 an hour as the crowd winds down; through hour 4 the pace eases to around 628 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 drivers order first
Wherever beer is served, Green Jar adds a case of 24 non-alcoholic beers per 100 guests without being asked. Designated drivers and pregnant guests hit the bar early, and the event that has an answer for them is the one they remember.
