(TMZ) Oakland A's catcher Bruce Maxwell -- the only MLB player who took a knee this season -- tells TMZ Sports he was confronted by a pro-Trump waiter at an Alabama restaurant who refused to serve him.
"He was like, 'You're the guy who took the knee? I voted for Trump and I stand for everything he stands for.'"
Maxwell says it all went down at a lunch with a local politician -- and after they complained to management, they got a new server.
But Maxwell says there's been a lot of POSITIVES that have come from his demonstration -- including a new friendship with Colin Kaepernick who's sort of mentoring him now.
