A Shake Shack customer appeared to watch the price of three milkshakes rise by 50 cents each after selecting 'no tip' at a self-service kiosk, sparking a viral debate over whether customers were being penalised for declining gratuity. But Shake Shack has now provided a different explanation for the unexpected price change.
The incident took place at a Shake Shack location inside Salt Lake City International Airport, which is operated by the chain's licensee, HMSHost. The customer, TikTok creator B.D. Powell, shared a video showing the ordering process, which quickly attracted more than 4 million views.
