"At one of the Lincoln-Douglas debates, Senator Stephen Douglas sarcastically referred to Lincoln's lowly beginnings. He allowed that his first meeting with Lincoln had been across the counter of a general store where liquor was sold. Douglas finally ended his remarks by saying, 'And Mr. Lincoln was a very good bartender too.'
"A roar of laughter erupted at this, but it quieted down considerably when Mr. Lincoln answered, 'What Mr. Douglas has said, gentlemen, is true enough; I did keep a grocery, and I did sell cotton, candles, and cigars, and sometimes whiskey; but I remember those days that Mr. Douglas was one of my best customers. Many a time have I stood on one side of the counter and sold whiskey to Mr. Douglas on the other side, but the difference between us now is that I have left my side of the counter, but Mr. Douglas still sticks to his as tenaciously as ever.'"
