Yes it still happens, but maybe not as much. Quite often whilst you think the captain is visiting the passengers doing good costumer service, they have actually been relieved by the 2nd crew, and if they are not feeling sleepy they will probably be bored and chatting to pax is a good way of stretching the legs and amusing oneself. Once flying back from Tokyo the Cpt even said in his welcome on board PA that we should not to be alarmed if we saw he walking about, there would be another set of crew still flying the plane! (just post Germanwings crash this was probably well worth mentioning)
