I'm trying to be sympathetic towards the interns.
Nope, not working.
I haven't worn a tie to work in 40 years, and at this point, don't own a suit.
However, if you set foot on a drilling location, there is still a dress code: Hard toe shoes/boots, NFPA 2112 compliant outerwear, hard hat, eye protection, gloves, hearing protection where appropriate, breathing protection where appropriate, grooming to allow an effective seal with air packs (in case of H2S).
There is always a 'dress code'.
