A viral TikTok video claims that a Shake Shack location penalizes customers for not tipping. The video, which has gained millions of views, alleges that the restaurant increases prices for items when a tip is declined. The incident reportedly occurred at a Shake Shack inside an airport, where a couple ordered shakes and declined to tip at a self-serve kiosk.

After doing so, they were notified of a pricing update and found that each item had increased by 50 cents. Shake Shack has denied the claim, but further details are available from the source for those looking for more information on the matter.
