“Waiting for the other shoe to drop” (business idiom)

“Waiting for the other shoe to drop” is a popular business idiom. A person wears two shoes; when a person takes off one shoe and drops it on the floor, it’s expected that the other shoe will also drop. In the business world, for example, a company might announce a large quarterly loss (one shoe dropping) and then announce the layoff of thousands of employees (the other shoe dropping).
 
The August 11, 1905 citation below appears to be the original story. A person rooming directly above a nervous hotel boarder dropped one shoe loudly, but then quietly took off the other shoe. The nervous boarder couldn’t sleep, waiting for the other shoe to drop!

Waiting for the Other Shoe to Drop
Waiting for a related announcement or event to occur after an initial announcement or situation. When waiting for the other shoe to drop, one expects a pending situation to occur that is dependent upon an initial event; for example, waiting for a presidential nominee to indicate his vice-presidential preference.

16 April 1905, Chicago (IL) Daily Tribune, pg. D7:
“At one time we lived under a couple for months. The man came home ‘loaded’ half the time, and Mark Twain’s story about waiting to hear the other shoe drop was borne in upon me. He always knocked over a chair while preparing for bed, and I have waited in an agony of suspense for half an hour, listening to him prowling around in the dark looking for his nightshirt, for him to knock over that chair, and when it finally crashed down upon the floor I went to sleep happy.”
 
11 August 1905, Janesville (WI) Daily Gazette, “Had Waited and Waited,” pg. 4, cols. 2-3:
From Sentinel Hotel Column: “I had a peculiar experience in a little hotel up in the state last week,” said John Spearman of Chicago, at the Republican house. “I know the landlord pretty well, and whenever I visit his house he tries to give me a good room But this time when I registered he seemed put out about something, and when the time came for me to go to the room to which I had been assigned to he came over and said that he would like to have a little talk with me.
 
“‘I am sorry to have to do this, Mr. Spearman,’ he said, ‘but the only room I have to give you is directly over that of one of our regular boarders, who is an unusually nervous man. We never rent the room until all the others have been filled, and I must ask you not to make any noise, as you may rob the poor fellow of his entire night’s rest by a little carelessness.’
 
“I assured the landlord that I would be most careful, but before retiring I attended a theatre and when I came in I had entirely forgotten the circumstances. I sat on the bed and took off one shoe, which I dropped with a crush.
 
“Suddenly I remembered the nervous man below me. Without a particle of noise I got to bed and could only hope that the one shoe which I had let fall had not disturbed the invalid. As I was dropping off to sleep there was a knock at my door. I quietly got up and opened it, and discovered a man attired in a long bath robe.
 
“‘I trust you will pardon me for disturbing you, sir,’ he said, ‘but I have the room below you and am an exceptionally nervous man. I heard you drop your shoe some time ago, and ever since I have tried in vain to go to sleep. I fear I shall be unable to do so unless I hear you drop the other one, if it will not be too much trouble.’”

28 July 1910, Boston (MA) Journal, “Little Stories of the Town,” pg. 6:
Remember that perennial entertainer, the story about the insomniac, who stayed awake hours waiting for the noisy drummer to drop the other shoe?
 
12 July 1913, Boston (MA) Journal, pg. 6:
Being Boston bred and raised I have some red blood in my veins, so when I turned over for that last nap this morning like the man waiting for the other shoe to drop, I listened expectantly for some noise to show that it was the dawn of the nation’s birthday, but I was obliged to listen so long that I got wide awake and stayed so.
 
30 June 1918, Duluth (MN) News-Tribune, section 2, pg. 1:
THIS is a period of waiting. It is a hiatus with just enough doing to keep you on edge. A clever Duluthian fitted it with the story of the man who got the last room in a hotel of thin partitions. He was warned to be quiet as in the next room was an old man who was a nervous wreck. Of course he forgot and dropped a shoe. Instantly came a querulous voice: “Stop that—noise.” Gently the man placed the other shoe and crept into bed. In about 10 minutes the same voice, higher pitched, came through the wall: “For God’s sake drop that other shoe!” If only Germany would “drop that other shoe” it would be a great relief.
