BE SPECIFIC
I went into a fast food restaurant and ordered a hamburger. The menu on the wall listed a "hamburger" as having pickle, mustard and ketchup, and a "deluxe burger" as having all kinds of crap which I don't like on it. I received the deluxe burger, rather than the regular hamburger. I told the girl that I had ordered a hamburger and had received the deluxe burger instead. She told me, "You need to be specific."
