Sounds like a good idea to look at a few things. Start by timing the brew for each method you use, then watch the line to see if larger cups really slow people down. Tracking the order flow—how many people place an order before the first cup is ready—might give you the real bottleneck. You could run a short test with a few volunteers, jot down the times, and see which tweak gives the biggest jump. That way you keep the coffee quality, and the whole team gets a smoother start.
