I haven’t seen at tie at work since the last recent graduate came though. Usually a tie indicates “I’m not technical, so only ask me general product questions”.
Only wear a tie in the office if I have customers coming in.
The topic of discussion, though, was clothing choices for air travel - I choose to wear a collared shirt and slacks or "good" jeans.
Hate the jammies or gym shorts look (take a bus why don't you....)
