It would appear that it is a common thing for American Chinese Churches to have a whole meal after Sunday Worship Services. Usually at a very low cost if not free (some churches would have it free for first comers).
This concept of course, is to attract more people, however one wishes to put it.
This practice is so strongly rooted in this church culture that if one doesn't stay with any plausible reason, one is considered anti-social.
But then what is social? Is social talking about vain subjects? I would rather take a lazy nap than talking about "How are you...What's up...You know computer-Wah...you sing in Oratorio-Wah...want to hold my hands"
Nay, please, I have better things to do. Now that I can leave at will without any problem. Praise be to God. In my previous church, it would be a trouble if I leave on my own as I would have to walk to the train station and many would want to arrange rides for me or I would be trapped with vain chatters in the car.
