Contrary to common goals, Shake Shack's kiosks did not reduce labor costs. Instead, the company reinvested potential savings into higher-touch hospitality, like table-side food delivery. This enhanced the customer experience, justifying the larger order sizes that digital channels encouraged.

Shake Shack intentionally adopted a 'fast-follower' approach to kiosks. This allowed them to learn from competitors' R&D and implementation mistakes (like obtrusive designs), ultimately deploying a more effective and less costly solution without the risks of being a technology pioneer.

Instead of a single cart upsell, high-volume sites use a sequential flow. After a user clicks "buy now," they see multiple, distinct offers (e.g., a subscription, then an accessory) before they even see the final cart, maximizing Average Order Value.

When offering customizable products, customers get overwhelmed by choices. Instead of making them build from scratch, present a pre-configured, fully-loaded version as the default and let them remove features. This leverages social proof and simplifies the decision-making process, increasing conversion.

Instead of showing two final prices (e.g., $99 vs $169), frame the premium option as the base price plus a small add-on ("$99, or get everything for $70 more"). This 'differential price framing' focuses on the small extra cost, not the total, and can double premium sales.

The idea is to put a large, "ugly" QR code on all garbage bins by default. Customers are then offered the option to pay a recurring fee to *remove* the QR code. This reframes the standard product as a discounted, ad-supported version and creates a new, high-margin revenue stream from customers who value aesthetics.

Shake Shack found digital kiosks improved employee experience by removing the high-pressure, repetitive task of order-taking. This freed staff for more fulfilling hospitality interactions, like delivering food or offering recommendations, ultimately enhancing the guest experience.

Most people mistakenly try to upsell after a customer has received value. The correct timing is when their need is at its peak. You sell two steaks when the customer is starving, not after they've finished the first one, by amplifying their perceived lack before they've had their first bite.

By introducing a third, strategically priced but less appealing option (the "decoy"), you can manipulate how customers perceive value. A medium popcorn priced close to the large makes the large seem like a much better deal. This proves that value is relative and can be shaped by deliberate choice architecture.
