When the meeting descends into chaos, you need a plan.
1. Falsify your keyboard. Type "I've got a meeting" into every chat window, to confuse your coworkers.
2. Deploy your best "I'm on a deadline" face. This will give them an excuse to end the meeting.
3. Infiltrate the break room. Steal all the coffee. Leave a cryptic note: "I'm not a morning person."
4. Activate your emergency exit strategy: feign a sudden interest in the bathroom.
