title: Is it possible for use case to have different action depending on which Actor triggers it?
body: <p>Is UML allowing this?</p>
  
  <p>Can I define how an actor is interacting with use case?
  In other words, can an use case have a different action depending on who triggered it?
  For example in the following picture, Client pays for food, and waiter accepts the payment, but client and waiter are connected to the same use case. Wouldn't it be more convenient, to make separate use case called "Receive the payment" for waiter?</p>
