Donald Trump's Hotel Sued By Security Guard -- They Hated My Stubble

EXCLUSIVE

Donald Trump
's hotel is being sued by an African-American man who says his bosses put a razor to his neck with an ultimatum ... shave or get out of town.

Bryan Lambert claims in a new lawsuit he worked as a security guard at the Trump International Hotel & Tower in NYC. He says his bosses got on his case because he wasn't clean shaven. But Lambert says he had a good excuse ... he suffers from Folliculitis Barbae Traumatica -- aka Barber's itch.

Lambert says he tried explaining it's a common condition among black males ... which causes painful inflammation from ingrown hairs which is made worse when you shave. But he says his bosses didn't want to hear it.  

And this is choice ... he claims one of his bosses even said, "You are not special. Why can't you look more like Christine?" -- a female Asian-American woman who works the front desk.

He then throws in the kitchen sink with various allegations that he was threatened, disparaged and even had his locker vandalized. 

Lambert wants a cool mil minimum. 

The Donald -- who was not sued -- wasn't available for comment.
