I renamed our trash room “Waste Concierge” and slapped a 24x36 sign with a QR code to “book a pickup,” hoping for a cheeky brand lift and cleaner floors. Day two: 58 scans, most between 1–3 a.m., plus three residents tried to tip the “concierge” (aka the maintenance drop box). What clever labels have nudged behavior without creating a service expectation we can’t staff?
