A gag gift that bills them for their worst habit.
Everyone knows someone with a habit the rest of the group quietly pays for. The ECA Invoice itemizes it: the terrible advice they seem to follow, who paid and how much, and the Better Move that would settle the account. Printed and handed over, it gets read aloud.

Why an invoice works as a gag gift
A complaint can sound like a complaint. An invoice sounds like accounting, which is funnier: the habit gets a lesson name, a rung on the ladder, and line items for everyone who paid. The joke lands because the details are true and the tone is completely calm.
Who to bill
Pick a harmless habit the whole room recognizes: the reply-all coworker, the roommate whose pan is always soaking, the friend who is forty minutes late, the uncle who brought slides to the wedding. Shared jokes land; private grudges do not.
Occasions
White elephant and Secret Santa swaps, office farewells, retirements, birthdays and roommate move-outs. Every invoice ends with a Better Move and a small repair, so the recipient gets a way to settle up.
Example language from the recordItemized charges: half the office, for blankets at every desk, 12 blankets. The office manager, for a locked thermostat cover, 1 lock. Balance due: one week at seventy-one.

What is the ECA Invoice?
A satirical itemized invoice from the ECA series, the companion to the book The Everyday Common Asshole. It names the lesson the behavior is following, lists who paid, and offers a Better Move.
Is it a real bill?
No. It is a novelty document for entertainment. Nobody owes anything, except perhaps an apology.
How fast can I have it?
It is written as soon as payment is confirmed and opens right away to print or save as a PDF. You can edit the wording afterwards.
Can I keep it anonymous?
Yes. Your name on the invoice can be anything, including The Office or The Group Chat.
