The only reason we eat Chinese food on Christmas Eve is that non-Christian Chinese are the only ones who keep their restaurants open. We plan to eat Chinese this Christmas Eve.
I have read that the reason Jews love Chinese food and why they eat it on Christmas was:
1. Only Chinese restaurants where open on Christmas.
2. Non Christian Chinese where a group that did not bother Jews and who Jews didn’t feel threaten by as they did with Christians.
They had background instrumental music and one they played frequently was well known Christian music.
I've eaten a lot of Sesame chicken to "Amazing Grace" and "How Great Thou Art" being played on a piano.
