This is an INSANE story, and you can read the full thing at the link below, but I'll give you the cliff notes. One night at a restaurant in Huntsville, Alabama, Oakland A's rookie catcher Bruce Maxwell was out dining with a councilman and a friend. Long story short, one of Bruce's friends was carded for an alcoholic drink and produced an expired ID -- since it's against the law in 'Bama to serve someone with an expired ID, he was denied.
The friend made a huge fuss and told the waiter he was making everything and everyone uncomfortable (even though Bruce and the councilman seemed fine), and the waiter was switched to another table. The rest of the night went smooth after that.
Last week on TMZ Sports, Maxwell told his interviewers that he was denied service because his waiter identified him as the one player in the MLB that took a knee during the National Anthem last month, said that he voted for Trump and supports everything he stands for, and refused to serve him. The A's didn't comment and apparently Bruce is still standing by his story, but it's been refuted by multiple people.
