In the song, one sign discourages people with certain hairstyles from applying for employment. In a similar vein, those who don't grasp legibility's critical role in a sign's selling power scarcely belong among the ranks of sign professionals. In this age of computer-aided design, bad graphic layout is particularly inexcusable. Poor design frequently illustrates the politically incorrect truth that the customer isn't always right.
Some customers assume that, in terms of a sign's message, more is better.
Equally dangerous are customers with the temperaments, but not the talents of graphic designers. Locate the sign to facilitate unobstructed viewing from streets, roads or other thoroughfares. A sign of approximately the same size displaying only the business name with good color contrast is much more effective. Fifteen minutes of fame might be acceptable for TV, but for the signage medium, that's an eternity. Unless passing motorists can identify your customer's store within 2-3 seconds, the sign isn't doing its job.
