Task: Question Answering
Input (English): Context: We did n't make as much money ( probably partially since we closed up at noon - oh , and probably since someone took our signs down Friday night - once we got them back up ( around 9:30 ) things started to pick up ) but we got rid of a lot , and only had one ( very full ) vanload to take to goodwill . I call that a success ! Now if I can just keep myself from accumulating that much unneccessary stuff again ! ! !. 
Question: Why did having the signs down cause the speaker to make less money ?
Output (English): The customers thought the business was closed.
