GrubHub Was Getting 6000 Orders A Minute During Its Promo

A delivery app marketing campaign offering a "free lunch"-- aka a $15 promo code valid for three hours-- sent customers and restaurant workers alike into a spin on Tuesday as 1000s of orders jammed the system; disgruntled New Yorkers tweeted through their hunger pains.

GrubHub's New York City campaign on May 17 touted the physical and mental benefits of eating lunch.

Still, it yielded dozens of complaints, canceled orders, and service workers told a News they were "exhausted" trying to keep up.

In charge of packing orders at a Mexican restaurant in Harlem, a worker named Lily said that since the restaurant's delivery driver couldn't keep up with demand, she ordered an Uber and hand-delivered 11 orders herself.

GrubHub said that during the promotion that ran from 11 a.m. to 2 p.m., the app averaged 6,000 orders per minute.

" It got overwhelming," said Brandon Ching, working the counter at Greenberg's Bagels, a popular sandwich spot in Bedford-Stuyvesant, Brooklyn.

 "We were short-staffed today, so it really added extra stress to my day."

And customers were frustrated at the delays. Ebenezer Ackon told BuzzFeed News he was in 3,630 th places in line to talk to GrubHub's customer service when he gave up after waiting more than an hour for food and went to get something from across the street from his apartment.

Blake, who didn't want to use his last name, said the small Brooklyn cafe he ordered from received 200 orders in five minutes as soon as the promo began, so they reluctantly had to cancel orders-- including his.

"It's been a complete disaster," Nathaniel, a Manhattan resident who asked that his last name not be used

He'd been thrilled that his order from a highly-rated sushi restaurant went through, but after an hour of waiting, no response from the restaurant, and nothing from GrubHub, he canceled the order.
