Managed to bite my tongue in time.

It was early on a Sunday morning. Woman came in with nice clothes under her coat.

Customer: Where do you keep your Matzoh crackers?
Me: I am not sure we have crackers... i know we have Matzoh meal...
C: The website says its in with your international food?
Me: <walks her there> the Kosher set is right here.. and there they are!
C: Great, now, what Aisle do yo u have your grape juice in?

At this point it was all I could do from blurting out "So, Who forgot to buy Communion supplies?" but somehow i managed....

Matzoh crackers and grape juice for communion? Must be Baptist. That's what I remember going up.
