When i was in High School I would sell fireworks for some extra scratch. This was way back when a pack of baseball cards sold for 30¢ just for perspective... They were (and probably still are) illegal in Michigan, but my older brother would drive to Ohio by them by the gross and have me sell them for 15¢ a pack (of which he would give me a nickle). Of course I would sell them for 25¢ a pack netting me even more profit, but ultimately I needed to expand into more volume. So the football team's star linebacker walked up to my locker one day and asked how much for firecrackers. I quickly snapped off a deal "25 cents a pack, or 3 for a buck." Before I could facepalm what just fell out of my mouth, he snap called "give me 3".
Maff iz hard.
