NEW YORK — Your smartphone is the scourge of restaurants. Customers snapping photos of food and dawdling on Facebook at meals have slowed down table service by an hour over the last 10 years, as an anonymous post on Craigslist’s “rants & raves” section recently alleged. The writer claimed that his restaurant, located in Manhattan’s Midtown East and serving “both locals and tourists,” had studied security footage from July 2004 and compared with a tape of a recent Thursday this month. The takeaway: Today’s technologically distracted diners take longer to order, longer to eat and longer to pay — and then they blame the restaurant for the wait! “We are grateful for everyone who comes into our restaurant,” the aggrieved restaurateur wrote, “but can you please be a bit more considerate?”

In almost no time, the indignant and now deleted Craigslist screed set the Internet alight. A post on Distractify transcribing the entire complaint quickly racked up more than 750,000 shares and 2,600 comments. “Smartphone use in restaurants prompts Craigslist rant,” announced the BBC. “Cell phones slowing down service in restaurants. Wait times have doubled because customers are too busy with their screens,” blared the Daily Mail. “Why you should (really, seriously, permanently) stop using your smartphone at dinner,” proclaimed The Washington Post.

Tempting as it can be to take anonymous, unsubstantiated Craigslist rants at face value, we decided to do a little digging on this one. Let’s take a closer look at some of the specific claims made by the Craigslist post about customers in 2014:

— 26 out of 45 customers spend an average of 3 minutes taking photos of the food.

— 14 out of 45 customers take pictures of each other with the food in front of them or as they are eating the food. This takes on average another 4 minutes as they must review and sometimes retake the photo.

— 9 out of 45 customers sent their food back to reheat. Obviously if they didn’t pause to do whatever on their phone the food wouldn’t have gotten cold.

— 27 out of 45 customers asked their waiter to take a group photo. 14 of those requested the waiter retake the photo as they were not pleased with the first photo. On average this entire process between the chit chatting and reviewing the photo taken added another 5 minutes and obviously caused the waiter not to be able to take care of other tables he/she was serving.[end ital]

Three minutes to take photos of food? That’s a long time to take a casual snapshot or two. So is four minutes to take and review additional photos with friends, all while a presumably hot and delicious meal is sitting in front of you. “I think this is clearly a fake — the whole scenario is made up,” says Luke O’Neil, a food industry writer for publications including Slate who spent more than 10 years working in the restaurant business. “It seems like one of these things that’s designed to make a point.”

Smartphones have undoubtedly become a hot-button issue for the restaurant world in recent years. Some chefs have publicly decried phone pics and social media for ruining the dining experience, while others have banned the use of devices in their dining areas altogether. But is cellphone use really causing massive disruptions to restaurant service?

Roughly 30 percent of restaurant-goers take photos of their food, while 9 percent have paid for a meal through mobile.

“I haven’t noticed that,” says Patrick Duxbury, general manager at TAO Downtown in Manhattan’s Chelsea neighborhood. “We are a very busy restaurant — we service well over 600, 700, 800 diners a night — and I don’t necessarily think we’d be able to do that if smartphones were in our way.” As a common venue for celebratory dinners, birthdays and bachelorette parties, TAO Downtown does take lot of photos, Duxbury says, but that’s “absolutely not” bad for the restaurant. “Those pictures go up on social media, some of them instantly on Instagram and Facebook, and it gets us out there,” he says.

Other chefs, waiters, and restaurateurs echo this sentiment. John Kapetanos, owner of Ethos in Manhattan’s Midtown East — the same neighborhood as the anonymous Craigslist poster — says maybe 10 percent of his customers ask the waiter to take a group photo; it’s a favor that takes less than a minute and doesn’t slow down service. Over the 12 years Ethos has been in business, Kapetanos says cellphones have added maybe five to 10 minutes to the average table time, but that he doesn’t mind as long as diners at one table aren’t bothering those at another. Jean-Marte, a waiter at a French restaurant in Midtown who declined to give his last name, concurs that taking photos of customers doesn’t slow his stride. He adds that smartphones can even be quite helpful when dealing with foreign tourists who don’t understand the menu. “It’s easier for them to go on the website or on Yelp, and they can show you a picture and say, ‘This is what I want,’ ” he explains.
