Ways and Means

A man handed a pair of slacks to the department store clerk. "I'd like these altered, please," he said. The clerk asked for the sales receipt, but after searching his pockets, the man replied he han lost it.
The clerk informed him that it was store policy not to do free alterations without a receipt.
"Okay,then," the man said,"I'd like to return the slacks."The clerk processed the return and gave him cash equaling the cost of the slacks.
The man pushed the money back across the counter. "Now I want to buy the slacks,"he said. The clerk ranf up the sale, bagged the slacks and handed them to him with a receipt.
Triumphantly,he put the slacks and the receipt in the counter."I'd like to have these altered,please."
