Donald Trump's Twitter fight with T-Mobile's CEO

Donald Trump started a brief Twitter fight with T-Mobile CEO John Legere last week.

At first, Trump complained about poor T-Mobile service in New York. What Trump fails to realise is that you don't choose what wireless carrier is available in your building. The signals are blasted all over the city for any subscriber to use.

@realDonaldTrump @JohnLegere T-Mobile service is terrible! Why can't you do something to improve it for your customers. I don't want it in my buildings.

Legere responded by saying he wouldn't stay in Trump's hotel: @JohnLegere @realDonaldTrump I will serve all customers in the USA openly but I will obviously leave your hotel right away based on this. #checkingout

@JohnLegere @realDonaldTrump I am so happy to wake up in a hotel where every single item isn't labelled "Trump" and all the books and TV is about him.

Legere sent a bunch of other tweets poking fun at Trump, whipping up his followers to support him in the process, but you get the idea.

In the end, it's just a silly war of words between two high-profile businessmen.
