Good restaurateurs want to know when something goes wrong as soon as possible — while the diner is still in the restaurant, ideally — so they can fix it, and avoid a complaint in the future (or in the age of social media, a complaint that goes directly onto Yelp). For people who are used to communicating via email and text, speaking up about a cold plate of risotto can be somewhat anxiety-inducing. According to a recent survey by restaurant consulting group Technomic, 52 percent of millennials are uncomfortable sending food backat a restaurant (by comparison, 61 percent of people over 55 are comfortable doing so). They shouldn’t be! Restaurants want you to have a good experience! Hospitality is their business, and they want you to leave happy — and hopefully, come back again.
