It's generally not fine in other offices where cafes are already crowded just with employees (e.g. NYC). You have to register all guests at the building entrance and if you're registering lots of guests all the time, something might happen. What exactly I'm not sure; I don't know anyone who abuses the cafes to this extent. I think the registration requirements alone substantially curtail potential abuse.
