When Julie in Elkhart, Indiana saw this note from her roommate, Molly…

…she decided it was time to go on the offensive.

Then came the counter attack…

…and then Julie photographed the exchange and sent it to us.

Game, set, match.

Margarita spotted this note in the window of a laundromat in San Francisco. Honestly, she says, “I’m more afraid of a vindictive, threatening neighbor than a laundry ‘theif.’”

(And much love to our submitter Robin in Sydney!)

“We really don’t hate the holidays,” says our anonymous foreign-policy elf in Washington, D.C., “just passive-aggressive coworkers.”

Thanks to Sarah for capturing this delicious little slice of life from her Christian college in Illinois. (Delicious like a quart of Starbucks Coffee Almond Fudge, not one measly little low-fat Frappucino bar.)

Our anonymous submitter saw this note posted on the door to the walk-in cooler at a convenience store in Boerne, Texas. “The clerk told me that the Red Bull delivery guy had been drinking Red Bull and leaving the empty cans on the floor of the walk-in,” our submitter says. “In her words, ‘he was knockin’ himself off!’”

Casey from Shreveport, Louisiana spotted this on the Coke machine in the office break room. she clarifies: “Henry G.’s comment is in reference to the increase in price, not Katie’s wanting more Coke Zero.”

Meanwhile, Breanna in L.A. saw this somewhat amusing notice in a liquor store on the corner of Hollywood and Wine. (“Did someone pee on it?” she wonders.)

Writes Deanne: “Because Orlando prides itself on being a friendly city, we tend to do most of our dirty work via passive-aggressive notes and signs. This one is from the front door of a tacky tourist shop on international drive. I can get past the reference to ‘plane rude’ but the ‘Macdonalds’ analogy is a stretch.” (I’d add that characterizing this as a safety concern is a bit of a stretch too, but I think the amazing clip art and the hand-drawn smiley are what really push this one over the top.)

Adds Deanne: “I’ve never brought a Burger King bag into McDonald’s, but that’s not because of fast food etiquette, just lack of time. I did bring a Macy’s bag into a Sears store, and I’ve never felt the least bit guilty about it!”
