We all know John Legere takes no prisoners on social media. He tweets what he wants, when he wants and will quite happily antagonise his competition. But you can be sure he will never criticize his own customers. In fact, when it comes to CEOs on Twitter, there aren’t many that measure up to John’s engagement with his company’s subscribers.

So, when Donald Trump decided to call out John for T-Mobile’s “terrible” service, there’s no surprise in who Twitter backed up. It all started with Donald complaining about coverage, and asking John to actually do something about it. It just so happened that Legere was staying in one of his hotels – as a paying customer – at the time.

.@realDonaldTrump I will serve all customers in the USA openly but I will obviously leave your hotel right away based on this. #checkingout

The battle ensued, and is too long and full of many retweets to cover in its entirety. But it’s safe to say, John did check out:

.@realDonaldTrump checked out.. Now I don’t have to watch tv with the 1st 9 channels being the Trump family saying how wonderful they are:)

The most ridiculous part of this public fracas was Donald retweeting an image of John and his daughter out for a run, and calling the T-Mo CEO out for having bad hair. I mean, of all the things Donald Trump should go after, you’d think he would steer clear of any hair gags.

The world gasps and waits to see if @realDonaldTrump really just made a hair insult? Really? This is too easy..:) https://t.co/tKIA2uYe6B

It was pretty hilarious to read through, even if it was a little unprofessional. I think it’s fair to say that Trump got his backside handed to him. Be sure to ready through @JohnLegere and @realDonaldTrump Twitter profiles for the full picture. It’s fair to say, you won’t get this kind of value entertainment from Verizon or AT&T chiefs.
