What's The Rush?!

In the two months since my wife and I have decided to leave the Anglican Church for Catholicism, we have been to three different Catholic Churches. In these three churches I have seen the same thing happen. Something that, in my opinion, is cause for great concern. As the mass is nearing completion and the priest says the post-communion blessing, he then says that the mass has ended and to go in peace to love and serve the Lord. The people respond, "Thanks be to God!" And then we sing the closing hymn.

So far I have no problems.

My problem is, that before the hymn is even finished, people are rushing out the door in a hurry to leave church. Sometimes they leave as soon as the hymn starts playing!

Why the rush to get away from worshipping God? Will two minutes more of worshipping the Almighty God who created you really interfere with whatever you have to do on Sunday? Because if it does, then I suggest rethinking your priorities!

As messed up as the Anglican Church has become, at least they stay until the last hymn is completed. They aren't in a hurry to leave church as the Catholics I have seen are.

Are all Catholic Churches like this?

Why doesn't the priest put a stop to it?

Or better yet, why doesn't the priest say that the mass has ended after the hymn, when the mass has actually ended?!
