C'est du travail "synchrone", vous être "synchronisés" avec le serveur/cuisinier 👨‍🍳. Vous devez attendre 🕙 et être présent au moment exact où le serveur/cuisinier 👨‍🍳 finira les burgers 🍔 et vous les donnera, sinon quelqu'un risque de vous les prendre.

Puis le serveur/cuisinier 👨‍🍳 revient enfin avec vos burgers 🍔, après un long moment d'attente 🕙 devant le comptoir.
