For those who haven't read Cialdini [1], this is a refernce to a study which shows that asking: "Excuse me, I have five pages. May I use the Xerox machine?" lets you cut the line 60% of the time, but "Excuse me, I have five pages. May I use the Xerox machine because I have to make some copies?" Lets you cut the line 93% of the time. A more extensive quote from the book is [2].
