Bill stopped in at Abie’s little general store, looking for a bottle of mustard. The shelves were loaded with salt—bags and bags of salt. Abie said he had some mustard, but that he would have to go down to the cellar to find it. Bill went down with him, and there to his surprise were still more bags of salt. Everywhere he looked he could see salt.

“Say,” said Bill, “you must sell a lot of salt in this store!”

“Nah,” said Abie sourly. “I can’t sell no salt. But that feller who sells me salt—boy, can he sell salt!”
