Yes, again, and this is all hearsay, but it ABSOLUTELY did happen in the late 90s....

The story i always heard was it started as a thing between the Amish and Hasidic (in my mind when 2 guys bumped into each other shopping for hats), but the conflicting days of the Sabbath made it a logistic hassle.

So the Italians got involved, and were paid in flour.
