It's amateur hour if you can just plug in any random rpi, it gets a DHCP lease, access to the company lan, and a route to the outside internet.
However I don't mind being able to get LAN internet at a hotel that wants me to pay $24 per day for wifi when they have VoiP phones that have internet access...
That gives me internet and streamability/casting to the tv :)
Every single hotel I’ve been to in the last year or so has pitiful bandwidth, which is completely saturated after dark once everyone fires up Netflix and lets it run all night long.
Getting a route to the outside internet is not such a big deal; access to internal data is.
By the way: it's "amateur hour" if, as you say, that happens for a switch in a public/semipublic area in an office structure. On the contrary, I've seen a lot of "all-enabled" switches if those were accessible just from INSIDE the datacenter, where few people had access. It's not a really reasonable scenario.
