Bar workflow, mise en place, and service flow
A bar's physical layout either supports speed or fights it. The classic reference is the "movement triangle": the three points a barista repeatedly moves between — grinder/espresso machine, sink/steam wand, and the pass or POS — should be close enough that a barista can reach any of them in a step or two without crossing another barista's working path. Stations built around this triangle, with tools always returned to the same mapped position after use, let any trained barista work any station without relearning where things are.
Mise en place ("everything in its place") means the bar opens fully stocked and staged before the first order fires: syrups and milk to par, cups and lids within reach, tools clean and positioned — prep done ahead of demand, not during it, is what makes rush service possible at all. A practical way to size prep quantities is by daypart: instead of prepping to a vague daily total, size batches (cut fruit, brewed tea concentrate, ice) to what a specific segment of the day is expected to need, refreshing more often during predictable peaks rather than over-preparing early and wasting it late. During service, the standard sequence for a multi-item ticket is to start the longest-running element first (a blended drink, a batch brew, a slow syrup) and pull fast elements — especially espresso shots — last, so they never sit and go stale before the drink is finished.
When volume surges, splitting the bar into fixed lanes (for example hot drinks, cold drinks, and blended drinks) with one person per lane and a single voice calling tickets at the pass reduces the confusion and cross-talk that slows a team down far more than the order volume itself does.
