Real life example. I'm painting a bedroom today. Let's say I buy the paint from a store with a strict "no return" policy on paints. I want a green paint, quickly pick one out, buy it, and paint a wall in my room. I realize I hate the color. It's green, but its nothing like I expected. I take the rest of the paint back, demand that they take it back and give me a new can of a different green. The store reminds me of the strict "no return" policy on paint, but they are gracious enough to add some other colors to the partially used paint to try to fit my needs. I call bullshit and refuse to ever go to the store again. Even though I bought the paint without really seeing if I liked it, without buying a sample and testing it on my wall first, and knowing that the store rarely makes exceptions to their strict rules. Who is out of line in this situation? Me, or the store?
