You’ll get your own section: your tables, your guests. You welcome them at the table, offer advice on the menu, the Belgian beers, and the wines, take orders, and handle the bill. From the first recommendation to the final coffee, you are the face of those tables.
You manage the timing of your section: when a table is ready for the next course, when a dish needs to be served, and when a guest needs that little bit of extra attention. A Commis de Rang will support you. You’ll manage and train them, just as someone once showed you the ropes.
