They say that no good deed goes unpunished, and they may very well be right.
The athlete shared a picture on Twitter of a marine waiting in a terminal along with the caption, "I always give up my seat to military if my seat is better! I truly appreciate our troops #flyingtherightway."
He also posted the same picture on Facebook, writing, "He just doesn't know it yet but he will be sitting in this seat when he boards the plane I always give up my 1st class seat! #isalutethetroops!"
That's some incredible (and honorable) American spirit. But sadly, it turns out that Williams may have been fooled.
The website Guardian of Valor, which focused on ousting military imposters, has pointed out several reasons why they believe that the Marine in the picture is actually a fake.
They explain that "a Marine never wears a cover indoors unless he is armed" and "a Marine would never be at the airport in Dress Blue A [uniform], he wouldn't be wearing his cover while seated indoors, and he wouldn't be wearing a shooting badge on the right side of said uniform."
The site also reported that the same Marine was spotted in a Philippines airport on July 1 and was approached by a fellow flier.
The man reportedly told the flier that he had served in the military for over 30 years and deserved to wear the uniform.
