I am trying to use flic in a very specific commercial setting and would like to hear your ideas on how to best set it up.

Use case:

Two restaurants A and B share one kitchen.

When a dish for restaurant A is ready, the chef wants to discreetly "ring a bell" and call a waiter from restaurant A to come and collect it.

Same applies to a dish for restaurant B.

In each restaurant we have 3 waiters.

The goal is to have 2 flic buttons in the kitchen, A and B and whenever a dish is ready the chef clicks the relevant button and a notification is sent to the respective waiters. Ideally a vibration in their wearable (apple watch, or a cheaper wearable), or directly to their phone in their pocket.

How would you set it up?

Thanks!
