Secrets: What are you doing outside of work that could get you fired?!

What are you doing outside of work that could get you fired?! "I work at a hotel. I've snuck to a guest's room, after an invite, for a little unicorn." "Consuming the green good stuff." "A doctor at my work is doing procedures for cash outside work hours, but at work with the practice's supplies. I could get fired for not saying anything, but the doctor could fire me for telling."
