Where I live there is a grocery store chain that has this thing they call 'fuel perks.' For every $50 that you spend on groceries, you get 10 cents of per gallon of gas that you purchase from their gas stations. Obviously a good deal right now. In order to get the deal you must have a free 'advantage card' from the store which you scan before you purchase your groceries. In order to get the advantage card you have to fill out some paper work giving them your name, sex, birthdate, etc, so they can sell the marketing info (what you are buying) to interested parties. Give a little get a little.
The other day one of my friends told me that he was standing in line behind this old lady at one of those self checkouts. He sees the lady doesn't have an advantage card so he asks her if she wants to scan his so she can get discounts on her groceries (which she would) she says 'oh yes' and procedes to buy $100 worth of groceries, earning him 20 cents off in fuel perks. What do you think about this? Do you think doing something like this is unfair to the store or does it fall under the catagory of fair game?
