You want snark with those fries? No one is safe from Wendy's tweets

Wendy's Co. has come the mean girl of Twitter.

When archenemy McDonald’s Corp. in March announced it would begin using fresh rather than frozen beef in its Quarter Pounders, Wendy’s tweeted: “So you’ll still use frozen beef in MOST of your burgers in ALL of your restaurants? Asking for a friend.”

After Burger King tweeted about a five-for-$4 deal, a woman asked Wendy’s what it was firing back. “Edible food,” Wendy’s answered.

And when Hardee’s came out with a four-items-for-$4 deal, mimicking Wendy’s long-running four-for-$4 menu, Wendy’s tweeted, “We usually prefer the original to a knock off, but hey, you do you.”
