Writes out submitter, Erica: “I work in the Lower East Side of Manhattan, in a building comprised of a variety of offices and studios (fashion brands, art galleries, recording studios, artists, etc.) I find this note exceptionally funny, because in the three years I’ve worked in this building I’ve experienced the exact same rude, pompous behavior.”

Don is the organizer of a doughnut co-op in his Chicago office, in which each co-worker takes a turn bringing in doughnuts every Friday to share with the rest of the group. “One of my co-workers is notorious for cutting doughnuts in half and leaving the other half behind in the box,” Don says, “which annoys some of the other members of the co-op. Apparently a co-worker felt that I was failing to maintain doughnut discipline and took it upon himself to post this warning.”

Adds Don: “Half-doughnuts are no longer showing up.”

It was a Friday and Meredith in Lexington, Massachusetts was pretty much running on auto-pilot when she made the mistake of microwaving leftover tacos for lunch — FISH tacos. Much to her horror, Meredith says, “The smell immediately permeated the office and got everyone talking and wondering who had committed one of the worst office kitchen taboos — second only to burned microwave popcorn.”

In an attempt to make things right, Meredith says, “I then asked some software engineers, who like to bake frozen cookie dough in the toaster oven, if they would help me cover up my secret shame by baking some sweet-smelling cookies. This is the note they left for all to see.”

Writes Erica in New York: “I don’t think this woman is aware that the aggressive automatic flush makes water splash all over the toilet seats…but she’s obviously very angry.”

You might think that the writer of nearly a dozen couplets on toilet etiquette would include at least one variation on the sprinkle/tinkle theme, but apparently the poet at work in this Nassau County government building doesn’t go for in that sort of cliché.

But wouldn’t you know it? As Nicole from New York City reports, “The toilet seat in question was covered in ‘sprinkle‘ and absolutely disgusting.”

Writes Amber in Minnesota: “My friend works in accounting for a local restaurant chain, and every once in awhile she has to go through credit card receipts if something isn’t adding up correctly. She’s found some pretty interesting gems, but this one takes the cake.”

[Adds the Not-Pregnant Notewriter: THANKS FOR THE ‘TAKES THE CAKE’ COMMENT, AMBER. REALLY.]
