> doesn't sound unreasonable [...] if you were using a private companies space I've seen meetups, hosted by Amazon in Boston IIRC, where upon exiting the elevator, you were unexpectedly required to sign an NDA-ish contract in order to leave the vestibule. Now preregistration deadlines, signing in/out, license capture, headshots, and NDAs, aren't necessarily unreasonable for a company. Nor bag searches, nor surrendering electronics to lockers. But as expectations diverge, between "private companies space" and "I'm just here for a room of conversation and pizza", the energy barrier to attending, discomfort, and absence, may increase. Microsoft Boston in contrast, was built with access-control elevators and a floor of conference rooms, and so could provide "just name the meetup at the desk and go up".
