Those 2457 serves do not arrive evenly: the opening hour is the fastest, about 567 serves, because every guest wants a first drink at once; over hour 2 the bar settles into a steady 473 serves an hour; through hour 3 the pace eases to around 472 an hour as the crowd winds down; through hour 4 the pace eases to around 473 an hour as the crowd winds down; through hour 5 the pace eases to around 472 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.
