You'll rarely catch me doing this, but time at work. The other day my supervisor came in 28 mins late to meet with the night shifters. She was meant to be there at 6:30 am. I clocked out at 6:58 am, and of course she shows up a moment later and goes "oh good, you're still here! don't leave yet." I stayed 9 minutes for some bullshit that could've been in an email. That mf owes me $7 for my time.
