Então você vai ao balcão 🔀, para a tarefa inicial que agora está finalizada⏯, pega os hambúrgueres, agradece, e leva-os para a mesa. Isso finaliza esse passo / tarefa da interação com o balcão ⏹. Isso, por sua vez, cria uma nova tarefa, a de "comer hambúrgueres" 🔀 ⏯, mas a tarefa anterior de "pegar os hambúrgueres" já está finalizada ⏹.
