Challenge
A dozen dishes sold out at different times daily. Staff repeated the same answers all day and mistakes piled up at rush hour.
Solution
One tap on the POS and the dish greys out with a "Sold Out" badge across four screens, inside and outside.
Result
Customers know what's available before they sit down. Ordering flows faster and front-of-house pressure drops.
