Sure, you could ask this question—but you might not get an honest answer. “Somewhere in the back of every server’s mind is their check average,” Daniel Liberson, a former waiter, told Washingtonian. “At the end of the day, up-selling is critical—it’s how we’re paying our rent.“ae0fcc31ae342fd3a1346ebb1f342fcb Translation: If you ask your server for their favorite dish, they may direct you to some of the pricier options on the menu. That’s not to say they’re dishonest. While they might truly love both the steak and the burger, the steak might get the bigger push. If you’re really interested in choosing the most creative or delicious item, do some research ahead of time to learn the restaurant’s specialties or their most popular dishes (a quick skim on Yelp should suffice). So, this one is only true in certain situations. If you’re given the wrong dish or something inedible, then you’re well within your right to send it back and have it removed from the bill. However, you should never send something back simply because you don’t like it, and there’s nothing wrong with the food. “If a guest changes their mind after receiving a meal, it’s key to be upfront with the server and specific in terms of what exactly they didn’t like as the description of the item may need to be tweaked in the future,” Eric Marx, co-owner of The Wayfarer, told USA Today.

Just because they are kind doesn’t mean they want to go on a date. For The Takeout, The Salty Waitress notes you should ask yourself a few questions before you proceed to leave your number on a napkin: “What’s motivating you to ask her out in the first place? Do you know much about her? Has she shown any interest in you? (Note: Being polite is not an indication of sexual desire.)
