The line in front of the Butcher shop in Warsaw is long, indeed, and the people grow weary, ever more weary, of the wait. Eventually an official comes out and announces "We are very low on meat; all Jews must leave the line." So the Jews in the line quit the queue and head for home, empty-handed.
After some more of a wait the same official reappears and announces, "We are even lower on meat that we thought. All non-party members must leave the line." So all the non-card-carrying members standing in line begin heading for home, equally empty-handed.
After some more time the official appears to declare "All Serbs and Croats must leave the line; we haven't enough meat for you." Disappointed, they leave the line and wander off.
Well, you guessed it: a bit later the same official appears and informs the remaining people "Unfortunately we have run out of meat entirely - you may as well all go home," and disappears back into the store.
"Isn't that just the way it always is," mutters one old man as he departs. "Those damn Jews get all the breaks!"
