It sticks in people's minds.
But let's not pretend Novak Djokovich was thrown out of the US Open due to virulent anti Serbian bias.
It's because he acted like an angry child and smashed a tennis ball off a lines lady's throat while in close proximity to her.
That's unforgivable. Ask Denis Shapovalov. https://www.espn.com/tennis/story/_...s-undergoes-surgery-denis-shapovalov-eye-shot
No anti Canadian bias there. Just enforcing sensible rules.
Let's not forget Wimbledon where Tim Henman, as Establishment as any Brit player has ever been, was ejected when Alan Mills, an English man, a fellow country man, walked onto court to officiate the final ruling. Enforcement of rules against top players has been long overdue, cue for the FO to take notice and continue the clean up.
