Those 1920 serves do not arrive evenly: the opening hour is the fastest, about 548 serves, because every guest wants a first drink at once; over hour 2 the bar settles into a steady 457 serves an hour; through hour 3 the pace eases to around 458 an hour as the crowd winds down; through hour 4 the pace eases to around 457 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: a second bar is not half a team twice
Splitting one crew across two stations leaves both short. When Green Jar runs two simultaneous bars the floor is 3 bartenders, 2 barbacks, 3 runners and 1 glass cleaner, whatever the per-guest table says. Large events already above those numbers see no change.
