How Many Guests Can One Frozen Yogurt Counter Serve?

Every event enquiry eventually reaches this question, and a vague answer causes real problems on the day. Here is how the arithmetic actually works.

The throughput of a single tap

One frozen yogurt tap dispenses a standard serving in roughly fifteen to twenty seconds. Add the time a guest spends deciding, moving to the topping bar and assembling, and one guest occupies the system for about ninety seconds end to end.

That is not the same as ninety seconds per guest overall, because the stages overlap — one person is topping while the next is dispensing. In practice a well-run four-tap counter with a functioning topping bar serves roughly 120 to 150 guests per hour.

Why the topping bar is the real limit

The machines are rarely the bottleneck. The topping bar is, because that is where people slow down, deliberate and change their mind.

A narrow topping bar creates a queue no number of taps will clear. Widening the bar so three or four guests can work along it simultaneously does more for throughput than adding a fifth machine.

Planning numbers we use

The factors that change the maths

• Service window. Two hundred guests over three hours is comfortable. Two hundred guests in forty minutes is not.
• Whether dessert competes. If it is the only dessert, expect close to full uptake. If there is a mithai table too, budget for around seventy percent.
• Children present. Children take longer at the topping bar and often return. Weight the numbers up.
• Weather. A hot outdoor evening drives uptake sharply higher. A cold one drives it down.
• Counter placement. A counter people walk past uses far more product than one tucked into a corner.

Two things worth planning for

Split the counters if the venue allows. For very large events, two counters at opposite ends of a venue serve better than one large one, because they halve the walking distance and split the queue naturally.

Do not open at the start. Opening the dessert counter alongside the main meal makes guests fill up on it. Opening it slightly after produces a better rhythm to the evening and a more manageable queue.
