Pointless nitpicking of a solution - especially with a cover of SJW-style pretentiousness masked as inclusivity. Like if someone had responded to "maybe I'll provide sandwiches for the office lunch," with "not everyone can eat sandwiches - what if they can't lift the bread with their hands because they're disabled, or what if their religion forbids sandwiches, or what if sandwiches are a trigger?"
Sue: "So I suggested maybe the girls from bookclub would like a movie night to see the film of the book we just read, and Karen kept going on about how we needed to check to make sure there weren't any triggers in the movie, and see if we needed to post a flashing-lights warning."

Bob: "Does anyone in the bookclub actually need that?"

Sue: "No. She just likes being a Not Everyone Can Eat Sandwiches pain in the ass."

Bob: "I hear you. I got a guy at the office who says it would be unfair to offer team lunches as a reward for people because it excludes those who practice intermittent fasting. We don't even have anyone that does that - but hey, he says one day we might, and then that person might feel excluded."

The How I Met Your Mother euphimism for smoking weed, used to censor the act so that Ted can safely tell his kids.

"So there we were, eating a sandwich. The biggest sandwich we had ever eaten."
