That sounds kinda nice to me, actually. If I see someone going through a turnstile and their birthday is announced, I can shoot them a smile and a nice “hey, happy birthday”.
Little things to invite positive personal interactions between strangers can be a good thing. That is, perhaps, not the intended purpose, but it at least seems like a welcome side effect.
A very unwelcome side effect of that would be that I don't get to control it. It's obviously unnecessary for the service to be performed, but they decide to "invite positive personal interactions" no matter whether I want any of that at that moment in that place.
