Who spends and render accounts of church offerings? Any law for milking the weak and innocent people?

When you decide to visit a church and the service they provide, they in my opinion become too agressive to bring you into their fold, with the underlying desire to control and extract a pledge of 10% or more, that they love to call "love-offerings" There you are, trying to get your head and soul closer to God, and to be inconsequential about it, so you can talk to the Lord in a simple comfort, but no! they have to have someone come down the isle to pin a tag on you, so now you are being stared at, singled out, and being socialy forced to greet people you rather not greet just then. When you visit a bar instead of a church, the bartender does not place a visitors badge on you, nor will people at the bar run over to shake your hand, they are mature people that will nod, or just say a simple hi, or nice day, and let you keep your personal privacy, for what that's worth anymore. People that think they are just full of goodness, just do not consider to mind their own business,and just make you know, how good persons they are. The church should welcome you just as a bar does,for they both know the reason you came in, and allow you me-time to decide what drink you desire, or allow you to adjust your eyes to the church surroundings without spectacle.
