look at the likes in the screenshot between the posts, where the original Sunny D tweet works is that you can imagine it coming from the human behind the account and breaking the "script" or the "fourth wall", the other three tweets including Sunny D's "comeback" are all on-script, on-pattern
what Wendy's and Arby's have done so effectively with their twitters is lean in on either the account existing separately from the brand and being a responsive twitter account or being a living embodiment of the brand as if the brand itself were a human on twitter, most of the rest of the corporate twitters don't have good enough staff to pull that off because they're trying to be multiple things rather than create a character
this is also why the realDonaldTrump account works so well, they created a character that people can connect with
