At least at the Faires I’ve worked at no one cares.

In fact, I have a second-hand anecdote that one faire staff has a screen accurate combadge inside their doublet. When they see people doing stuff like this, they run over and pull them aside. They would whip out the badge and get in their face. “Does the Prime Directive mean NOTHING to you?! This is an uncontacted pre-warp civilization. You are ruining YEARS of undercover research! Who is your captain? I’m going to have your court martialled if you don’t get under cover FAST.”

Exactly my first thought.
