Sorted, Not Served

A Four-Tier Coffee-Queue Conduct Taxonomy Now Gates Express-Lane Access

A research poster from the School of Emergent Priorities reports an eleven-week observational study sorting coffee-cart queue conduct into a four-tier taxonomy --- order-readiness, device use, spacing discipline, and hand-off promptness --- scored live by two trained raters. Tier-A conduct at the two carts granted express-lane eligibility rose from 22 to 41 per cent of observed events over the following four weeks, and the responsible facilities panel has adopted the taxonomy as the standing, published basis for lane access, reviewed each teaching period with no individual override.
