Legendary Bulls reporter Sam Smith revealed the insane story this week ... saying players told him MJ would make airline stewardesses skip Grant on team planes after games if he sucked earlier in the day.
"Players would come to me over the years and said, 'You know what he did? He took Horace's food away on the plane because Horace had a bad game,'" Smith said on the Tolbert, Krueger & Brooks Podcast.
"He told the stewardesses, 'Don’t feed him, he doesn’t deserve to eat!'"
Of course, Jordan and Grant won A LOT together -- so it's unclear how often MJ pulled the savage move ... but it's well known the two didn't exactly have the best relationship regardless.

Their friction has been touched on several times in ESPN's "The Last Dance" documentary ... with Jordan even accusing Grant on the show of leaking stories in the '90s to paint him in a bad light.
For his part, Grant says he wasn't the snitch ... claiming, "Not one thing I divulged to Sam Smith."
