This shocking video shows an Uber customer unleash an expletive-loaded, xenophobic rant at his driver when he was asked to put on a mask inside the cab.
In the uncomfortable five-minute clip, the man, who claims to be a New York City firefighter, repeatedly swears at the driver and refuses to wear the "bull****" mask.
The customer demanded to know where his driver was from and then called him a "f****** foreigner".
