Have you ever intervened on behalf of a server?

I’ve never corrected someone at my table for their demeanor toward a server, although I have apologized for the conduct of my table. So the idea of correcting a diner at another table is slightly mortifying to me.

But the other night, while watching a woman blame her server for failing to remove cheese from a dish — despite her neglecting to ask that this be done (the conversation in the adjacent booth was loud enough for me to hear their order and everything else) — I thought about defending the poor, bewildered server.

Have you ever intervened on behalf of a server or restaurant when faced with a fellow diner who is clearly wrong?
