The worst one for me was the guy who didn’t wash his hands after using the restroom. One day, one of my team members told me about this, and I didn’t believe him, ha ha, so a few days later I’m in the restroom and this guy comes out of a stall and just walks out the door.

You said stall so I am onboard with your disgust. This always reminds me about a Richard Feynman story where he'd stand in the bathroom and ridicule people who washed their hands after using the urinal, saying the urine was sterile anyway.
