Two of the bigger personalities on Twitter got into a slugfest Saturday, with T-Mobile CEO John Legere taking on real estate mogul and occasional politician Donald Trump.
It appeared to begin with Legere complaining about street musicians playing right outside his room at one of Trump’s hotels in New York City.
Trump responded with a tweet criticizing T-Mobile’s service.
“T-Mobile service is terrible!” Trump said. “Why can’t you do something to improve it for your customers. I don’t want it in my buildings.”
And then Legere said he was checking out of Trump’s hotel.
“I will serve all customers in the USA openly but I will obviously leave your hotel right away based on this,” Legere said.
