Step-by-step explanation:
The question pertains to the hospitality industry and specifically what three things should be mentioned to a guest before walking away from the table after seating them. It's important to inform guests of relevant information that will enhance their dining experience. For instance, the waiter might want to highlight any specials or promotions the restaurant is currently offering, which can pique the interest of the diner and potentially upsell the restaurant's offerings. It is also courteous to inform guests of who will be taking care of them by pointing out their server, so that they know who to expect at their table shortly.
Lastly, the waiter should point out the location of essential amenities such as the restroom or the emergency exits, ensuring that guests feel comfortable and safe during their visit. This approach can significantly enhance the guests' dining experience and reflect positively on the restaurant's customer service ethos.
