Waiter Calling System

Technology is around us all the time nowadays in a first class resturant you wouldn't need to call the waiter any more , with a press of a button , you can call the waiter . Some times you can let the waiter know what you want , for example there are some devices that has ( check please , Order, ..) and so on.

Idea :
When customers push a button, the relevant member of staff's pager is alerted and a message shows where the customer is and what service they require.

Applications:
You might have seen it more resturants ,however it can also be applied in Clubs, /coffeeshops and Office Buildings>
