Sure, but what I'm saying is that the rationale behind this is not clear to me. What makes a personal device magically different than an audio tour? I believe sometimes cooling units can be required for specific people in workplaces yet those are not "personal devices"... and that doesn't get into they myriad of potential accommodations a person could potentially say they require outside of personal devices. Maybe they need cooling stations, sensory areas, anxiety decompression spaces, etc., etc.
Again, I'm not saying anyone is doing anything illegal. What I'm saying is that the laws regarding what needs to be covered come off as a bit random to me. I think they stem from a time when the word "disability" was used rather differently, to describe a few specific conditions.
