Beggars can't be choosers, or so we're told

We finally got the food set out and people were ready to go through the line. We were serving our usual bagels, cereal and fruit. As the group filed through, people were asking if we had any plain bagels or cinnamon raisin, or if they were lucky a cranberry bagel. Someone was upset that we ran out of plain bagels and was complaining to the volunteer serving. From somewhere in the back of the line a person yelled,"Quit holding up the line! Beggars can't be choosers."
