On Time, by a Later Clock

A Single-Site Case Study of a Suburban Alterations Shop's 48-Hour Guarantee, Whose Definition of When the Clock Starts Changed Twice in One Quarter to Hold the Same Compliance Number on the Receipt

A paper from the School of Emergent Priorities audits one suburban alterations shop's point-of-sale timestamp logs against its own change history for the internal setting governing its 48-hour guarantee's clock start, finding the shop's reported weekly on-time rate held flat (M = 87.5%) across a business quarter while an audit fixed to the guarantee's advertised drop-off anchor shows on-time performance falling from 87% to 61% to 47% as the setting changed twice (N = 914 garments). The hours added to the clock start track the shop's own growing backlog closely (r = .91), and the pattern is unchanged when rush-fee garments are excluded from the audit.
