Seems totally normal to me. In the past people would have come into work with this attitude predominantly I think. Work is a place you work to have money to live your life. For better or worse that norm changed a bit, but I think more and more people seek it out as they get tired of all the meaningless, only semi-voluntary socialising they have to do for work.

If you're in a place that allows this kind of interaction, then I'd say cherish it. It's far from the only one, but lots of places now try to pretend like everybody needs to be bestest buddies and want to spend even more of their precious lives in each other's company.
