Worst Inattentive Players

I wanna hear about the worst inattentive players people have had in their games, what did they do? what ended up happening to them?

I had a player in our campaign who would just have their character autopilot whatever the party does and only chime in when loot was mentioned, low and behold I find out after the campaign ended that they had just been playing games on their laptop the whole time, they tried to argue they had ADHD but were kicked from the core group before the next campaign began.

Especially annoys me when they don’t actively engage or care about the game while you’ve got other people lined up who would love to play the game.
