An Amazon Just Walk Out-powered autonomous store opened this week in the cafeteria at Lake Washington Institute of Technology, marking a new deployment for 365 Retail Markets and Pacific Northwest operator Evergreen Refreshments — and signaling continued momentum for frictionless retail in the campus foodservice channel.
How the Store Works
The format occupies a full walkable retail footprint — a step beyond a standard micro market kiosk or locked smart cabinet — giving students, faculty, and staff broader product selection without a staffed checkout lane. Shoppers tap in at an entry gate using a credit card, mobile wallet, or the 365Pay app; overhead cameras and shelf sensors build a virtual cart in real time; and payment processes automatically when the shopper exits. No cashier, no line, no self-checkout terminal.
For Evergreen Refreshments, which operates more than 1,000 micro markets across Seattle, Portland, Olympia, and Spokane, the deployment addresses two persistent pain points in campus foodservice: peak-hour congestion and off-hours access. Lunch rushes that once produced abandoned transactions — lost revenue for the operator — now clear faster because throughput is no longer gated by a single point-of-sale station. The store also replaces what were previously vending-only windows with a full assortment available at any hour, a meaningful upgrade for a campus that runs evening and weekend programming.
Integration and Support Model
As a member of Amazon's Just Walk Out Certified Partner Network, 365 Retail Markets handled the full site build — design, camera calibration, gate setup, and installation — and serves as first-line support through its existing field teams, escalating to Amazon for deeper hardware or technology issues. Critically, the store connects directly into the 365 platform Evergreen already uses for catalog management, payment processing, and reporting, avoiding the parallel-system problem that has slowed autonomous retail adoption among smaller operators.
"This store gives them a place to grab what they need, any time of day, without ever waiting in line," said Arthur Siller, SVP of Business Development at Evergreen Refreshments. Jeff Dumbrell, Chief Revenue Officer at 365 Retail Markets, framed the deployment as evidence that autonomous formats can match the operational tempo of busy campuses — handling high transaction volume at peak without proportionally scaling labor.
Broader Operator Context
The campus foodservice segment has become a proving ground for unattended and autonomous retail technology, as operators face ongoing pressure to extend service hours without adding headcount. 365 Retail Markets — which expanded its operator footprint significantly following its acquisition of Cantaloupe, Inc. in May 2026, adding that company's payments, telemetry, and device network to reach nearly 40,000 operators nationwide — is positioned to replicate this model across its existing client base. For regional breakroom and refreshment service providers like Evergreen, the Just Walk Out integration offers a competitive differentiator against both traditional vending and the growing field of smart-cooler and micro-market rivals.
The Lake Washington deployment also illustrates a go-to-market approach increasingly common in the micro market and campus dining space: a technology platform acting as the single-accountability partner for build, integration, and ongoing support, while the local operator maintains its customer relationship and existing back-office workflows.
