A sign stood on the sidewalk just outside a tavern on Valencia Street in San Francisco. The sign read, "Open At [blank], Happy Hour til [blank], $[blank] off." The blank areas were available for the person in charge to chalk in the details. The price still displayed a painted over number 2 for "$2 Off." The time following the "til," had been covered in tape and later painted over with the same color as the background. On the whole, this sign was a great example of ambiguous information.
