Some office environments too.

Last place I was at, I worked nights pretty much solo. If my wireless earbuds died, sure, I’d play it out loud. I was the only one in the building. About an hour before anyone else started getting in, if my ear buds still hadn’t charged enough I turned it off.

Partially to be respectful, and partially because some people get offended by metal even if they can’t understand the lyrics. And I mean, yeah, some bands can have unprofessional lyrics. I get it having been in the working world so long.
