Dentist office I went to has a private room with an Echo, they use it to switch playlists without having to touch anything, I guess. Figure they didn't really think it through....
But yeah I was a bit uncomfortable with that. Not that anything private was discussed, I simply had a cavity filled. They're excellent dentists tho, best I've ever seen, so I won't be going elsewhere.
In my experience with "mentioning the potential privacy issue" people are aware, it's just an awkward conversation that they'd prefer not to have.
Imagine being a receptionist at a dentists office and some whackadoodle rolls in to the waiting room on their electric scooter, and loudly exclaims... "are you aware that you and all of the staff here are absolutely completely 100% butt naked under your clothes and hosiery? It's unhygienic, unsanitary, non-inclusive, and completely unsatisfactory. I just thought you should know and perhaps talk it over with your boss".
Your reaction to this hypothetical scenario is the reaction you can expect when talking to your dentist about privacy.
Yeah, don’t go looking too hard whenever you’re in a hospital or anything. The number of vulnerabilities I can spot with as little infosec knowledge I have is deeply concerning
