Counter and drive-thru
Separate queues with their own number prefix, so B-12 and D-12 never get mixed up.
Restaurants and cafés
The counter, without the pager pile.
Customers order, scan the receipt or the counter card, and sit down. When the kitchen is done you tap Ready and their phone rings.
Table numbers
Customers can add their table while they wait, so staff can bring it over instead of calling.
A menu link while they wait
Your menu or dessert list one tap away from the ticket.
Ratings that help
After pickup, one tap to rate. Four and five stars are invited to Google Maps; anything lower goes to you only.
