Keep the serving part simple.

One pot: schedule tasks by equipment

List brewing, filtering, topping preparation and cleaning as separate tasks. Work that uses the same pot must happen in sequence; weighing, labeling and arranging cups can happen alongside it.

• Check working capacity, not the vessel’s brim-full volume.
• Prepare a receiving jug before filtering starts.
• Confirm suitable holding space for every ingredient.

For example, if you need 3.15 L filtered tea and a trial batch produces 1.5 L, plan three batches, with the last batch covering the remaining amount. Dry tea, starting water and filtration loss still need product-specific confirmation.

If the schedule does not fit, reduce the number of cooked toppings or serve smaller batches. Do not extend steeping time to compensate for insufficient equipment.

Self-service: one route for guests, another for refills

Arrange cups → optional toppings → drinks → straws and napkins. Refill from the side or behind. Walk through with an empty cup to find points where guests would need to turn back.

Give each topping a separate utensil and label the actual ingredients. Keep packaging available for guests to inspect; do not guess at “dairy-free” or allergen-free claims. Separate utensils are not a guarantee against cross-contact.

If two people are helping, assign one to the guest area and one to mixing and replenishment. With one host, reduce choices rather than trying to watch several containers at once.

Extra guests: calculate the shortfall first

Check remaining liquid, unused cups and guests still waiting. Divide liquid volume by liquid per cup and round down; check ice and toppings separately.

If each cup needs 400 mL liquid, 2 L covers five cups. With eight guests waiting, the shortfall is three cups or 1.2 L liquid, plus the matching cups and ice. Extra ice does not create the missing liquid.

If ingredients and equipment allow, prepare another measured batch and explain the wait. If using smaller cups, tell guests and recalculate. Do not add unplanned water simply to increase cup count.
