As a computer science professor, I had a notable bright student who relished his bright-blue hair and deranged attire. One day, instead of seeing him arrive, there was a new sensibly-dressed fellow with jet-black hair. Ooops, same guy. Seems he nailed an interview for a really interesting job - but was told he didn’t get it because of his unprofessional appearance. Kid learned fast the hard way.
Good lesson to learn.
A few years ago, we had an after hours company function. Our intern got himself rip-roaring drunk and it really wasn’t pretty.
Several of us, including a couple high level execs separately took it upon ourselves to have a conversation with him and counsel him that even after hours, you’re still on duty and need to act like it.
A former employee, who was probably let go ultimately because of his drinking passed out and froze to death in his driveway a couple years before that incident so this kid was shown that he was going down a bad path.
