When some old guy is at your desk for ten minutes after you fixed his problem, warbling at you about how it's not fair that having bad eyesight means you can't still be a pilot?
you can stealthily open google voice on your computer and fake a phone call to your desk so that oops, sorry, chat time is over, gotta pretend to talk to someone about an email now
also keep in mind this dude was like, easily 80, or at the very least aged so badly as to not be able to tell it apart, so bruh your pilot's license is LONG gone
