Where order grouping is captured, it can show whether selected drinks commonly appear together or in larger rounds. That helps explain preparation demand, but it does not prove why a group chose them or how each recipient felt about the drink.
Read combinations as service evidence
Compare round size and drink combinations with the menu offered at that time. Note whether a welcome-drink arrangement or restricted selection shaped the orders before treating a combination as a spontaneous preference.
Use recurring patterns to organise ingredients, glasses and the working sequence for a similar event. Keep orders, serves and guests as separate concepts. Anonymous records cannot identify repeat customers, and a large round should not be presented as several independently observed buying decisions.
- Check the order-grouping method before analysing combinations.
- Keep any explanation of preference clearly separate from observed counts.
