There's a 7-11 back in the town I grew up in that was frequented daily by a little girl named Suzy that would buy 10 bottles of lemonade; 2 for her and the other 8 to give to her friends and family. It got to a point where she bought so much lemonade that the store started stocking more and more, to the point that the amount of lemonade they would keep on hand meant that they stopped stocking things that other people wanted to buy.
