Our anonymous submitter spotted this signage at a homemade water park somewhere near Cherry Point, South Carolina.

Dealing with the rantings of your crazy boss or overzealous receptionist is one thing, but what do you do when your office’s resident passive-aggressive note-leaver doesn’t even work there? Casey in San Diego (a.k.a. RunBarbara) says that’s the situation she’s found herself in at her job.

The offender, Sandra, “has met me a total of twice, both times for less than a minute,” Casey says. Yet for some reason, when Sandra (the aunt of the owner) stops by the office once a week to water the plants and drop off supplies, “she leaves these strange notes EVERYWHERE — and she almost always directs questions about said notes to me,” Casey says. “I often have no idea she posts these notes until someone asks me about the odd directions in them.”

Below, a small sampling of Sandra’s delightfully bizarrre directives. (Just click on the photos to enlarge.)

I’d like to think this note was posted immediately following the “potluck”…

“Beware,” indeed: Walking along “West 25th or so” in Manhattan, this “work of art” was enough to make Eric “personally” “shit his pants.”

Mishee was about to go ahead and just pay for that Snapple…until she saw this colorful little note at a drugstore in Sunnyvale, California. Phew!

UPDATE: Mishee (ever the overachiever) has returned to the scene to satisfy your curiosity about the signs behind the signs…and finds her Snapple-drinking plans foiled in the process!

My own neighborhood of Park Slope, Brooklyn has high concentrations of dogs, babies, crazies and bloggers, which makes for a heady brew of incredibly well-documented passive-aggressiveness. Certain notes (like this long-running series) show up in my inbox over and over again. I’ve gotten various iterations of this note from no fewer than six different people over the past few months, with good reason.

I think the dogged persistence of the note-writer is pretty incredible in its own right, but even better is what the note doesn’t quite explain: these bags weren’t just being stolen — some “juvenile/adult delinquent” was also cutting the bottom of the bags, then putting them back for the next unsuspecting dog-walking victim. Oh, shit!

(Thanks to William, Kathleen, Elaine, Sarah, T-1-11, and JM for submitting!)

aarwenn from seattle found this note in her office’s cafeteria, which she says is a hot spot for bad writers with passive-aggressive issues. “of course,” she says, “here at Large Aerospace Company, a lot of us have ‘issues.’”

This series of signs (all made by one person, and pinned up across an entire bulletin board) is among my all-time favorites. The glorious redundancies, the inappropriate quotation marks, the clip art — oh, it’s just too good.

(Yeah, the last one is blurry. Our anonymous Canadian submitter apologizes.)

This exercise in mass shaming is brought to us by Rocky in San Diego, who notes: “These are 5-year-olds playing T-ball.”
