Ever notice how it is never a quick question after that phrase? Heck, even on GT, some guy asked "Just a quick question, what caliber is best for self- defense." At work when someone asks "just a quick question," it seems they are belittling what is involved in arriving at the answer to the question they are asking. For example, "Just a quick question, how many more people will vote for Romney than Obama? Oh, and break that down by state, race, and gender."
