Regarding the latter: We Charismatics and Pentecostals are generally non-liturgical and regard ourselves as "Spirit-led," which in this case includes the possibility that from time to time the Spirit may lead us to have an "all music" service. At other times it may be no music and extended teaching from the Bible; or littler or no music or teaching, but mostly ministry by congregants by the gifts of the Spirit. In the large majority of cases there will be an arranged order that will include all those components, but never rigidly fixed that way.
Regarding the former: I think this reflects a liturgical, sacramental, "high church" mindset. It is what YOU consider "normal," but is not necessarily THE norm. Charismatics and Pentecostals are generally non-liturgical and non-sacramental (so of course we don't view the Lord as resting in the plate even in those services which include Communion). While socializing (or "fellowship") is not the focal point, we regard the Church as "the body" of Christ, and so interacting with each other is not an adjunct, it is a legitimate part of "worship" itself.
Yes, I have a high-church mindset. Before Vatican II, every Catholic did. I don't expect non-Catholics to worship the way Roman Rite Catholics do at the Traditional Latin Mass. What non-Catholics do at their services is up to them. I've been to many of those services, too.
But think of it this way. For a Catholic, Our Blessed Lord is still sacramentally, transubstantially present in the tabernacle, even when there's nobody else there in the church. So we believe He's already in the building before Holy Mass begins. People run around the church to fellowship, they distract other people who try to pray silently. With all the fellowshipping, it's as though most people there ignore Our Lord.
Years ago, when I still attended the New Mass, a folk group began to sing the Our Father after the priest started to say it. They should have said it, too. Sometimes I wonder what performers would do if Christ walked into their church. Would they say, "Please be quiet now, sir. We're performing?"
From my perspective is man-centered, partly because the priest faces the congregation. During the Traditional Latin Mass everyone faces the same direction to face Christ. The priest isn't being rude with his back to the congregation.
But I can hardly help thinking about rudeness when I remember something my favorite priest told me before he died. In Roman Rite Catholic churches, the tabernacle's usual place of honor has usually been the middle of the high altar, where the faithful could see it the moment the walked into the church. At the church I used to go to, he needed to say the English Mass at a portable altar on wheels with the tabernacle behind him and on the high altar. During the English Mass there, rubrics required him to lean down to kiss the altar. He refused to do that, though, because he hated to show Our Lord his, the priest's, backside. If I bended over to show another parishioner mine, I probably would offend him.
