Donald Trumploves him some McDonald's, but ain't so keen on paying for it ... at least according to a former bodyguard who claims he's still $130 in the red, thanks to DT.
Kevin McKay says he worked as Trump's bodyguard for 5 years ... and one time in 2008, after visiting one of his golf courses in Scotland, their convoy of 6 Range Rovers hit up Mickey D's before flying home.
Thing is ... McKay says Trump didn't have any UK currency, "so he asked me if I could front him the cash." McKay says he did, and ordered 20 cheeseburgers and fries and around 10 to 15 Cokes.
McKay told the Daily Mail ... Trump ate his usual fave -- 2 cheeseburgers with fries and a diet coke. McKay says $130 at the time was kind of a big deal to him, especially because he only made around $2,700 a month while working for Trump.
McKay says he should have asked for the money, but kept blowing it off ... and Trump never brought it up either. Trump's McDonald's obsession is widely known. You'll recall he served a McDonald's buffet to Clemson and North Dakota State after they won football national championships.
McKay was fired in 2012, and he claims the stress of working for Trump ultimately cost him his 23-year marriage. And, $130 too ... allegedly.
