App idea for restaurant/hospitality industry

Hey, so I’ve worked in the industry for 15 years, and I always thought it would be a cool idea for my restaurant to give away a free (alcoholic) shot to customers once the chefs/kitchen/kitchen staff are out of food. <br><br>I think it would be cool to have a management operated app that when the business is out of food, it sends out a notification to all of the customers in the restaurant. Then I would want to have a QR code on each table that would link to the app and when you scanned it, you’d see a list of drinks that are available (manually inputted by management). When you agree to the terms and conditions, it sends a request to the bar. <br><br>How it would work with management and the bar is when you agree to the terms and conditions, you’d see a list of pre selected drinks on your phone, you’d select the drink you want, and it would send a notification to the bar. Once you agree and it’s sent, the notification sent to the bar would have the table number I guess so that the bar would know where to send the drink. <br><br>Let me know if this exists or if anyone wants to develop it!
