Big Uproar
There was once a big uproar at some sporting event where the venue had an exclusive deal with Aquafina or Dasani, and they HAD to sell only that water. Any vendor on premise was forbidden from selling any other bottled water.
So the vendors started doing this: They posted signs saying, “Single peanut for sale, $1, free water bottle included with every peanut purchase.” Genius.
